Abstract

Abstract:

This paper proposes a suppression method of the deceptive false target (FT) produced by digital radio frequency memory (DRFM) in a multistatic radar system. The simulated deceptive false targets from DRFM cannot be easily discriminated and suppressed with traditional radar systems. Therefore, multistatic radar has attracted considerable interest as it provides improved performance against deception jamming due to several separated receivers. This paper first investigates the received signal model in the presence of multiple false targets in all receivers of the multistatic radar. Then, obtain the propagation time delays of the false targets based on the cross-correlation test of the received signals in different receivers. In doing so, local-density-based spatial clustering of applications with noise (LDBSCAN) is proposed to discriminate the FTs from the physical targets (PTs) after compensating the FTs time delays, where the FTs are approximately coincident with one position, while PTs possess small dispersion. Numerical simulations are carried out to demonstrate the feasibility and validness of the proposed method.
