Through-wall Radar

Through-wall Radar (TWR) is a portable handheld RADAR used for the detection and location of static and/or moving targets, especially humans behind solid barriers or walls. It is ideal for Defense and Homeland Security applications that require through-wall detection of living and non-living things.

The TWR is ideal for locating hostages in a building where all modes of communication links are shut off. In such hostile situation, the rescue operators may have to spend a considerable amount of time to locate the hostages. TWR facilitates rescue operators with the much-needed situational awareness and aids them in locating people and weapons in the building.

The Through-wall Radar comprises of an RF Subsystem, Signal and Image Processor, Radar Controller, Display/HMI, Wireless Video Transmitter and wideband Transmit and Receive Antenna that operate in the L and S-Bands. The TWR uses a Stepped Frequency Continuous Wave (SFCW) radar architecture operating at 1-4 GHz band, with a range resolution of 5cm.

The TWR HMI includes a 400 x 100 pixels screen that supports 2D Display and Time v/s range display. The HMI has multiple physical buttons for Power on/off, Range selection, operating mode selection, Wireless transmission, System reset and Playback among others.

The Through-Wall Radar operates at -20⁰C to +55⁰C and is qualified for IP65 and MIL-STD-810-F for thermal, humidity, rain, vibration and shock operations. The TWR has been developed by Mistral in collaboration with LRDE-DRDO. Mistral has received Transfer of Technology (ToT) certificate to upgrade, manufacture and sell the product in India and abroad.
