In over-the-horizon (OTH) radar, the frequency band is limited by crowded and powerful interference. It is difficult to find an uncontaminated and broad band, which leads to low range resolution and signal-to-interference and noise ratio (SINR). A de

For target movement without velocity information in a passive coherent location system, the unknown Doppler shift between the direct signal and the target echo results in a decrease of the highest peak output value and the occurrence of some false pe

An inverse QR iterative algorithm is derived for calculating practical adaptive weights based on the space-time multiple-beam (STMB) approach. It is suitable for improving the detection performance of the STMB approach in all interesting ranges. Simu

This paper deals with an approach for improving the ability of radar to resolve targets by increasing an equivalent array antenna aperture and decreasing its equivalent beamwidth due to the motion of targets. The theoretic analysis is presented, the
