Array Radar Life Detector LSJ-ARD

Figure 1: A single LSJ-ARD radar node — compact 250 × 120 × 52 mm body, 1.8-inch OLED status screen, acoustic/optical alarm indicator and external WiFi antenna.

Figure 2: Four LSJ-ARD nodes cascaded into one wireless array. Each node weighs under 1 kg and is simply positioned at a separate monitoring point — scaling from four-in-one to eight-in-one kits.

Figure 3: The English-language tablet interface — four conical radar views, connected-radar count, a No./Status/Power table (detect / move / stop), target distance readout, plus SETTING and STOP ALARM controls.

Figure 4: The screw-down sealed rear enclosure of an LSJ-ARD node, built to IP65 for dust ingress, rain and rubble-field handling between -20°C and +60°C.

Figure 5: Search-and-rescue crews work a night-time collapsed-building site. LSJ-ARD nodes can be left monitoring the rubble while crews coordinate the next excavation from the command tablet.

Figure 6: The four-in-one LSJ-ARD kit in its waterproof, dustproof hard case — four radar nodes, the rugged tablet bay, antennas and accessories in custom-cut foam for transport and storage.

Figure 7: Complete LSJ-ARD delivery set laid out — radar nodes with antennas, rugged tablet terminal, removable batteries, smart charger and waterproof transport case.

A: The LSJ-ARD is a wireless array of radar life-detector nodes that locates living people trapped under earthquake rubble, collapsed buildings, landslide debris and snow. It detects breathing and slight movement without contacting the victim and reports target distance and status to an 8-inch rugged tablet over WiFi.

A: Yes. The LSJ-ARD detects the chest-wall breathing and micro-movement of stationary (non-moving) living targets, so an unconscious or trapped survivor does not need to move, speak or signal to be found.

A: Each node penetrates at least 50 cm of solid wood block or concrete brick and operates through brick-concrete and concrete walls, floor slabs, ruins, timber, snow and open air — all non-metallic, low-moisture obstacles — with a selectable range of 5 m or 10 m per node.

A: Each node covers a 90° horizontal effective angle (±45° three-dimensional cone) with a ≤0.5 m positioning error, enough to direct an excavation team to the right point on the rubble pile.

A: Standard kits are four-in-one or eight-in-one configurations; custom node counts are available on request. All nodes connect wirelessly to the single 8-inch display and control terminal by WiFi, which lists every node’s status and battery.

A: The 680 g, 8-inch 1280 × 800 rugged tablet shows a real-time conical radar view for each connected node, the connected-radar count, a No. / Status / Power table (detect, move, stop), target distance, and SETTING and STOP ALARM controls in an English interface.

A: Nodes run on removable dry batteries, rechargeable batteries or a battery pack, with a smart charger included. Continuous operation is rated at ≥5 h per battery set, with cumulative field endurance of more than 7 days across multi-power deployments; battery level is shown on the OLED screen and tablet.

A: Yes — every node is sealed to IP65 (waterproof and dustproof) and is rated for a working temperature of -20°C to +60°C, and the complete kit ships in a waterproof, dustproof hard case.

A: Each kit includes the display and control terminal, four or eight radar nodes with antennas, batteries, a smart charger, the instruction manual and a waterproof transport case. Send LSJ your deployment scenario (site size, number of search points, 5 m or 10 m range) via the inquiry form to receive a configuration quote, MOQ and lead time.

Tell us your deployment scenario — four-node or eight-node kit, 5 m or 10 m range — and LSJ will prepare a configuration quotation for your team.
