Advanced airborne radar may require adaptive space-time processing (STP) to detect small targets at long ranges. STP is a multidimensional adaptive filter that resolves received radar data into a spectrum of plane waves in angular and Doppler frequency coordinates. The platform of an airborne radar can scatter incident signals into the antenna, spreading the spectra of the clutter signals so that...
Large ultralow sidelobe airborne array antennas are required for detection of low radar cross section targets against a background of complex clutter and jammer interference. One of the critical factors which limits the clutter and jammer suppression performance of adaptive phased-array radars is the impact of the aircraft in the near-field of an ultralow sidelobe antenna. A simulation featuring a...
The authors study how internal clutter motion, channel mismatch, platform interaction and nonstationary jammer multipath limit the effectiveness of an airborne adaptive radar. Approaches to mitigate these effects are discussed.<<ETX>>
