Sidelobe Blanking with Generalized Swerling-Chi Fluctuation Models

The work presented here focuses on the performance analysis of the sidelobe blanking (SLB) system with noncoherent integration in the presence of white Gaussian noise and jammer entering through the sidelobes of the antenna. Closed-form performance probabilities, in terms of either the generalized Marcum or Nuttall Q-function, are derived for nonfluctuating target and jammer, both in the blanking and the detection regions. The analysis is then extended to account for arbitrary correlated, possibly nonidentically distributed, fluctuating target and/or jamming returns among a given number of integrated pulses. Finally, several numerical results are given, and the effects of typical SLB parameters are discussed.
