Recent research has shown that effective jammer and clutter suppression is best performed with fully space-time adaptive processing. However, allowing adaptive weights on every tap on every element is computationally prohibitive and requires too many samples to converge. Eigenvalue analysis shows… More

The extension of classical frequency domain and wavelet transformation adaptive subband decompositions result in arbitrary time frequency til. The use of a time-varying tree-structured filterbank is proposed to provide a signal dependent transform which is capable of tracking non-stationarities via… More
