LD-RIII Through-Wall Radar | Life Detector for SWAT

Core Capabilities

See Who Is Behind the Wall Before You Enter

A portable UWB radar helps tactical and rescue teams assess occupancy, target position and posture before entering a room or unstable structure.

LD-RIII radar host for through-wall detection

CAPABILITY 01

Long-Range Through-Wall Detection

Low-power UWB pulses penetrate concrete and solid brick while clutter-filtering algorithms suppress wall reflections and environmental noise.

Detects moving targets at up to 20 m and stationary targets at up to 10 m through concrete and solid brick
True 3D X/Y/Z positioning with ≤1 m error and ≥120° wide-angle coverage
Detects ≥3 targets with standing/crouching posture identification (≥80% within 5 m)

CAPABILITY 02

True 3D Positioning

Live X/Y/Z coordinates, 3D visualization and moving-target trajectory tracking show where people are located behind the wall.

≥120° conical coverage supports wide-area scanning
Tracks at least 3 targets simultaneously with real-time coordinates
Standing/crouching posture recognition reaches ≥80% within 5 m
Moving targets are reported within ≤5 s; stationary targets within ≤10 s

LD-RIII 3D through-wall radar target coordinates interface

CAPABILITY 03

Wireless Command Display

The 8-inch display and control terminal weighs no more than 1 kg and communicates with the radar host wirelessly over at least 20 m line of sight.

Shows target position, count, trajectory, posture and host battery
Keep the radar on the wall while the team monitors from cover
Supports single-operator stand-off operation

CAPABILITY 04

Built for Harsh Field Conditions

The radar host is designed for dusty outdoor operations and water-jet exposure, with shock-absorbing armor and a compact mission-ready kit.

IP55 dust protection and water-jet resistance
≤8 kg host including battery and terminal
Operating temperature from −20°C to +60°C

LD-RIII live 3D wall scan target interface

CAPABILITY 05

Fast, Trustworthy Alerts

Clutter filtering and human-target recognition support rapid tactical decisions in complex wall and rubble environments.

Moving targets reported within ≤5 seconds
Stationary targets reported within ≤10 seconds
≥90% detection probability with ≤10% false alarms

CAPABILITY 06

Single-Operator Mission Kit

The standard configuration combines the radar host, wireless terminal, tripod, spare battery, charger and hard carrying case for rapid deployment.

Tripod-mounted stand-off monitoring mode
Handheld wall-press scanning mode
No signal cables between the operator and radar host

APPLICATIONS

3D Through-Wall Radar For Tactical Rescue

Applicable to municipal fire services, industrial emergency teams, hazardous-materials sites, and wildfire response units, subject to operational requirements.

Structural firefighting and search operations

Counter-Terrorism & High-Risk Entry

Confirm room occupancy, count and posture before high-risk entry or structural search.

Hostage and barricade response with stand-off radar monitoring

Hostage & Barricade Incidents

Use stand-off radar monitoring during barricade incidents and structural searches where line of sight is blocked.

LD-RIII urban search and rescue deployment

Urban Search & Rescue

Locate stationary living persons after earthquakes, collapses and structural failures where direct line of sight is blocked or unavailable.

Operational Scenario

Locate People Before You Enter

The scenario below illustrates how the LD-RIII can support a through-wall search. It is not a documented customer case study.

LD-RIII deployed on a wall during a search operation

Map Occupancy, Position and Posture

Situation

A collapsed or obstructed structure blocks direct line of sight and makes room occupancy difficult to assess.

Potential use

A team can place the LD-RIII against a wall or mount it on the tripod, monitor target count and 3D coordinates from the wireless terminal, and plan entry or rescue decisions before committing personnel.

Decision support

Findings may inform search priorities and structural risk discussions under the incident commander's procedures. Outcomes depend on conditions, training, and additional equipment.

Frequently Asked Questions

Procurement and Deployment

Answers to common questions from fire-service procurement teams and end users. Confirm all commercial and technical terms with the supplier.

How far can the LD-RIII detect people, and how accurate is it?

Moving targets can be detected at 20 m or more and stationary targets at 10 m or more through concrete and solid-brick masonry. Three-dimensional positioning error is no more than 1 m on the X azimuth and Y range axes.

Can it detect people who are not moving?

Yes. The LD-RIII can report stationary targets at 10 m or more through concrete and solid-brick masonry. Confirm wall structure and deployment conditions during application testing.

What is included in the standard LD-RIII kit?

The standard package includes radar host, 8-inch terminal, tripod, hard carrying case, spare battery, charger and cabling.

Can we arrange a demonstration or request tender documents?

Contact the supplier with your organization, intended use, quantities, and delivery market. Ask about demonstration availability, a compliance matrix, test reports, and manufacturer authorization where required; availability and terms must be confirmed in writing.

What warranty and calibration support is available?

Request written warranty coverage, service turnaround, spare-parts availability, and recommended calibration intervals in the quotation. Inspection and recalibration may be advisable after severe heat exposure or impact; service terms depend on the purchase agreement.
