Time Domain has released a compact (3″ x 4″) UWB radar module with 1.4GHz bandwidth at a 4.3GHz center frequency. From their website:
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 unit comes with a pair of Broadspec UWB antennas. Elsewhere, I described the genesis of this UWB dipole antenna. The 310C Planar Horn Antenna provides a directional alternative to the omni-direction behavior of the Broadspec antennas.
