The GPS Bistatic Radar Delay Mapping Receiver (DMR) is an airborne bistatic radar receiver developed at NASA Langley Research Center (LaRC). It measures the direct, line-of-sight, right-hand circularly polarized (RHCP) signal and the delayed, earth-reflected, near-specular, left-hand circularly polarized (LHCP) signal from a GPS satellite. These measurements can determine surface properties such as soil moisture, ocean surface winds, and sea roughness. DMR operates at the L-band frequencies of 1.57542 GHz and 1.2276 GHz.
