HXSAR-5KS Portable Slope Stability Radar | 5km GB-SAR

Core Capabilities

ArcSAR on a Rotating Base, Not a Rail

A portable ground-based radar that measures slope deformation without touching the slope. Eight kilograms, one operator, a first scan in under two minutes — and 360° of azimuth from a single set-up point instead of one face at a time.

CAPABILITY 01

True 360° Coverage from One Set-Up Point

A rotating circular synthetic-aperture platform replaces the linear rail of conventional GB-SAR. One position covers the full azimuth, so the radar no longer has to be moved and re-levelled every time another sector needs watching.

360° panoramic azimuth per scan from a single stand-off position
Vertical coverage to ±45°, from a powered tilt of −30° to +30° combined with a 30° antenna beam
No rail assembly and no repeat survey set-up when the watch sector changes

CAPABILITY 02

Sub-Millimetre Deformation, Read out to 5 km

FMCW microwave radar resolves cumulative displacement, velocity and acceleration on the slope face at ranges up to five kilometres, and the software also tracks crack development across the scene.

Deformation accuracy quoted as sub-millimetre level — request the test conditions, reference targets and observation interval for tender review

CAPABILITY 03

Non-Contact, and Immune to Traffic on the Face

Nothing is installed on the slope: no prisms, no sensors, no cabling. The radar measures from a safe vantage point, and personnel, haul trucks or machinery moving across the face do not corrupt the deformation record.

Operators stay off unstable ground — the instrument is set up beyond the failure zone
Vehicle and personnel movement inside the scene is stated not to affect the measurement
Suits operating benches, waste dumps and tailings bodies that cannot be closed for a survey

CAPABILITY 04

Rated −40 °C to +55 °C, Day or Night

FMCW microwave imaging is stated to be unaffected by rain, snow, fog, dust, glare or darkness, and the unit is rated for operation across −40 °C to +55 °C — the weather window in which optical monitoring usually stops working.

Penetrates vegetation cover, where optical and laser systems lose the surface
Identical measurement principle at night and at noon — no illumination or target lighting required
Ingress protection rating is not stated in the available material; request the IP figure and the operating humidity range in writing

CAPABILITY 05

8 kg, Under Two Minutes, North Found Automatically

One person carries the system in a folding case no longer than 0.8 m and reaches a first scan in under two minutes. A GNSS satellite compass, inclinometer and attitude sensors align north and level the unit, so no survey crew is needed on site.

Set-up by a single operator — no crane, no rail, no survey team, no prisms on the slope

CAPABILITY 06

Unattended Early Warning through ASSR-Lite

The browser-based ASSR-Lite platform applies yellow, orange and red displacement and velocity thresholds, performs extreme-value detection with nobody watching the screen, and pushes SMS alarms to the duty phone.

Monitoring a slope that is already moving?

Send the slope height, the stand-off distance you can work from and the warning lead time you need. LSJ engineers will confirm the configuration and the achievable resolution at that range.

Applications

Built for Every Slope That Cannot Afford to Fail

Emergency response, mining, dams and infrastructure run on the same portable unit. The source material groups the work into eight fields; the three most common groupings for a procurement brief are below.

Landslide and Post-Earthquake Response

Secondary-failure risk after an earthquake or days of rain. The radar stands on stable ground at the road head or on the opposite bank, and the first scan is available while teams are still working below.

Mines, Quarries and Tailings Dams

Highwalls, waste dumps, benches and tailings dam bodies monitored continuously without stopping haulage. One unit covers several faces in 360°, where separate linear scanners would otherwise be needed.

Application fields of the slope stability radar: mountain slope landslides, hazardous rock masses, excavation pits in construction and mining disasters

Rock Masses, Excavations and Long-Term Networks

Unstable rock above a road, foundation pits and retaining walls, and municipal geohazard networks that need a repeatable record over months. The field types shown in the source material are mountain slope landslides, hazardous rock masses, excavation pits and mining disasters.

Field Record

Deployed When the Ground Was Already Moving

Four emergency deployments between 2022 and 2025 are stated by the manufacturer, including a warning raised ahead of a secondary landslide that was carried by CCTV-13 and Xinhua News Agency. These accounts are supplied by LSJ and have not been independently audited.

Example: Zhenxiong, Yunnan — Alarm Before a Second Collapse

Situation

On 23–26 January 2024 the radar was deployed at the Zhenxiong landslide in Yunnan, where the remaining slope above the search area was still moving. Rescue teams and heavy plant were working inside the run-out zone, and the ground had to be watched continuously for a second failure.

Potential use

The unit is set up outside the moving mass, the 360° azimuth is aimed at the unstable sector, and yellow / orange / red displacement and velocity thresholds push SMS alarms to the command post. Nothing is fixed to the slope, so the monitored sector can be changed without sending anyone onto the debris.

Decision support

The manufacturer states that an alarm was raised before a secondary landslide and that the operation was reported by CCTV-13 and Xinhua News Agency. The other recorded deployments are the M6.8 Luding earthquake (September 2022), the M6.2 Jishishan earthquake (December 2023) and the Junlian landslide of 8 February 2025, where the unit supported the China Anneng Chengdu Base. Treat these as supplier-reported references and ask for site reports before relying on them in a tender.

Frequently Asked Questions

Accuracy, Weather and Deployment

Answers to the questions geotechnical engineers and procurement teams raise first. Confirm all technical and commercial terms with the supplier in writing.

How is this different from a conventional rail-based GB-SAR?

It uses rotating ArcSAR architecture instead of a linear track. One set-up point gives 360° of azimuth, the complete system weighs 8 kg and the manufacturer states a first scan in under two minutes. A conventional rail-based GB-SAR weighs considerably more, needs assembly on site and covers only one facing at a time.

How accurate is it, and how far can it monitor?

The manufacturer states sub-millimetre deformation accuracy at ranges up to 5 km across a full 360° azimuth, reporting cumulative displacement, velocity, acceleration and crack development. Resolution degrades with range and depends on the observation interval, so ask for the accuracy figure at your actual stand-off distance rather than the headline value.

Does rain, snow, fog or darkness stop it?

No, according to the manufacturer. FMCW microwave imaging is stated to be unaffected by rain, snow, fog, dust, glare or darkness, it penetrates vegetation, and the unit is rated from −40°C to +55°C. An IP rating is not published in the available material, so request the ingress protection and humidity figures before specifying it for exposed sites.

How fast can it be deployed in an emergency?

One person moves the HXSAR-5KS from its folding case to a first scan in under two minutes, as stated by the manufacturer. The built-in GNSS satellite compass aligns north automatically and the inclinometer and attitude sensors level the unit, so no survey crew or prism set-up is required.

How does early warning work, and can it run without internet?

Operators set yellow, orange and red displacement and velocity thresholds in ASSR-Lite. The platform performs unattended extreme-value detection, pushes SMS alarms, and generates daily and weekly reports. ASSR-Lite uses a browser / server architecture and can be deployed on a local network as well as in the cloud, on Windows or Linux with Chrome, Edge or Firefox; a connection above 20 Mbps is recommended for smooth remote viewing.

What is still unconfirmed before a tender?

The available material does not state the ingress protection rating, power supply and consumption, runtime per power source, physical dimensions, packed weight, scan rate, or warranty and calibration terms. Standard shipment documentation is CE (LVD & EMC), ISO, MSDS and RoHS. Request the missing figures and the product-specific test reports in writing before submission.
