Abstract
This study deals with the target detection problem embedded in multiple range jamming which is usually employed to mask the useful signal or deceive the radar systems. Exploiting the observation that the waveform of the range jamming would be not identical to the probing signal of the radar system, the authors propose a coupled sequential estimation algorithm to obtain simultaneously the range profiles of target and jamming. Each iteration of the proposed algorithm designs a set of linear filters for each range bin based on the minimisation of the output average power by utilising the obtained range profiles of target and jamming at the last iteration. The proposed algorithm is capable of eliminating the jamming in the target range profiles and shares very low range sidelobes. The numerical simulations are provided to prove the effectiveness of the proposed algorithm also in comparison with the matched filter.
