Software – Radar/Channel Analysis
Radar Sensing & Channel Analysis
Our Monostatic Radar Module (MRM) software configures our UWB modules to operate as fully-coherent, short-range monostatic radar sensors. In doing so, the P440 and the full-bandwidth P452 achieve the most RF bandwidth (>1 GHz) and the lowest possible center frequency (4.3 GHz), with performance comparable to 10 and 20 GHz systems but at a fraction of the cost and with much better propagation characteristics.
Ultra Wideband Radar
The MRM software enables you to pursue radar applications which require:
- Exceptional clutter rejection
- High resolution (1.4 GHz bandwidth provides resolution <6”)
- Short range operation (a few inches to hundreds of feet) with minimal blind range
- Increased gain with increasing operating range
- Highest possible RF bandwidth at the lowest possible operation frequency
- Fast update rates (up to 20 kHz)
- Access to raw radar scan data allows tailored filter and detection strategies targeted to specific applications
The MRM software opens the door to a wide variety of compelling uses, including Synthetic Aperture Radar (SAR) imaging, tagless people tracking, obstacle avoidance, drone altimetry, and proximity sensing. In each case the signal processing is different based on the application. We provide a feature-rich API with sample C and MATLAB code to aid programmers in their development efforts.
Radar Modes of Operation )))
MonoStatic Radar Module (MRM)
Our OEM module is a very flexible UWB Radar Front End that repeatedly provides the RF impulse response of a volume defined by the unit’s antenna pattern. The Monostatic Radar Module Reconfiguration and Evaluation Tool (MRM RET) is a host application that operates on a PC and exercises all of the radar API commands. It displays raw radar scan data in real-time, showing the distance and reflectivity of targets within the scan range, and can also log the radar scans to file for post-processing. MRM RET includes algorithms that support motion filtering and detection processing, however we encourage users to optimize these algorithms for their own application, using the provided sample C and sample MATLAB code.
Channel Analysis Tool (CAT)
Use as a Propagation Tool: Because the transmitted signal contains a high precision embedded synchronization clock, there is no need for a hardwire trigger signal between the transmitter and receiver. This eliminates an operational limitation of typical systems. A CAT-based system will collect high quality propagation data faster, more conveniently, and at a tenth of the cost of a conventional DSO-based system.
CIR provided: CAT is also provided with sample MATLAB code that uses the CLEAN algorithm to convert captured waveforms into Channel Impulse Responses (CIR).

Communications Statistics Provided: CAT provides communications statistics for all received data including: Eb/No, Bit Error Rate and Packet Error Rate.
Multistatic Radar
Use as a Bi- or Multistatic Radar: Waveforms captured by CAT can also be treated as Bistatic or Multistatic radar waveforms. All energy subsequent to the first arriving energy is caused by reflections from targets in the field of view. Reflections that change over time are moving targets. Collected data can be converted into I&Q data streams and Doppler processed. Waveforms can be motion filtered and processed for detections.
