Zusammenfassung:	Techniques to improve the detection and mitigation of synchronous and asynchronous interference in radar signals. The corrupted received signals can be processed to reduce the effect of interference, while preserving existing targets. Various can use a two-step approach to (1) detect and mask the corrupted samples, and (2) recover the masked-out samples. The recovery step enforces sparsity of the existing targets and prevents target smearing, which is a common problem after interference mitigation. The sparsity enforcing recovery step can preserve small targets while successfully rejecting interference. The techniques do not require any prior knowledge of the parameters of the interfering radar.
