The single-channel module consists of one transmit and one receive antenna with the FMCW frontend on the backside of the multilayer PTFE board. It is optimized for small size and low weight: (2.5x3.5)cm², 5gr.

Multi-Channel (Tx2Rx) Frontends

For applications that require an angular resolution of targets IMST offers multi-channel modules. These modules have multiple receive (Rx) antennas in a very compact array design. A dual channel (2Rx) module with IQ mixers is directly available. Modules providing a larger number of channels can be developed on request.

Application

AirRobot^TM applies our Radar modules for obstacle avoidance manoeuvers in UAV micro drones.

Our partner IHP has developed a SiGe MMIC implementing full RADAR functionality. The chip is embedded into IMST’s TxRx frontend, taking advantage of the antenna’s excellent properties. The system is intended for low cost and high volume applications within the ISM band. For initial testing the frontend is fully compatible to our high performance baseband module and software, but may be combined with a cost-optimized alternative.

The baseband module carries the digital processing units and implements the communication with the user system.

Depending on the systems mounting position the module may be connected with USB cable or to a WIMOD module. Accordingly the system can be directly powered by USB or battery pack to enable full mobility. IMST has developed an additional software package that enables the user to perform out-of-the-box measurements. The software establishes the data transfer and performs a variety of signal processing steps, including tracking and clearance algorithms.

These routines are already implemented on the controller of the baseband module and are ready to be applied by the user.
