Abstract

Adaptive signal processing strategies have to be developed for cancellation of electromagnetic noise-like interference in modern radar systems. The authors compare two signal processing methods, the least squares (LS) and the total least squares (TLS) algorithms, for adaptive phased-array radar systems. Results are presented which show that the TLS algorithm has a slight advantage over the LS algorithm at a cost of more computation. The LS algorithm therefore remains the preferred processing method.
