PulsON® 400 MRM:The World's First Coherent UWB Radar Module
Time Domain’s PulsON® 400 (P400) Monostatic Radar Module (MRM) is a fully coherent, short-range radar that packs 1.4 GHz of RF bandwidth in a small, low cost, low power OEM module. The P400 MRM achieves the RF bandwidth normally associated with 10 and 20 GHz systems but at a fraction of the cost. This bandwidth provides the resolution required to achieve clutter rejection for operation inside buildings and in other complex environments. Operating at a low center frequency of only 4.3 GHz, the MRM also enjoys much better propagation characteristics. All together this gives the MRM the most RF bandwidth and the lowest possible center frequency.
The P400 MRM is a high performance RF engine that provides raw radar scan data so that you can develop filtering and detection strategies targeted to your specific application. To help you get started, the MRM includes sample C code, sample MATLAB code, and a Reconfiguration and Evaluation Tool (MRM-RET) that allows quick analysis of the radar’s performance with a variety of bandpass filters, motion filters and detection algorithms.
MRM-RET Provides Raw, Bandpassed, Motion-filtered and Detection Data (actual screen capture)
The P400 MRM is ideal for monostatic 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 operating frequency
- Fast update rates (up to 20 kHz)
- Access to raw scans allows tailored filter and detection strategies matched to specific applications
To deploy UWB enabled products, you need a cost-effective, easy-to-use, and easy-to-customize UWB module, which is exactly what you will get with the P400 MRM. Better yet, the P400 MRM uses the same hardware platform as the P400 RCM. This opens the door to addressing applications that require radar, ranging, and wireless communications.
For those experienced with full featured UWB, your wait is over. The P400 MRM includes our latest generation of silicon and represents the culmination of everything we know about UWB.
We are excited about helping you create new UWB enabled products and applications. If you need assistance, we have an experienced contract services team ready to help. Contact us today.

Architecture and User Interface
The P400 MRM provides all of the hardware and software controls necessary to configure the radar and collect raw data for use with a standard detection engine (MRM Service) or with your own custom signal. The Host communicates with the MRM through a simple, easy-to-use Applications Programming Interface (API) that allows development of a radar system tailored to a specific market need.
