Abstract

Abstract

In radar system, the target-induced interference often arises due to multipath effect or non-ideal transmit waveform of Multiple-Input Multiple-Output (MIMO) radar. For the issue of detecting a target with target-induced interference, the detectors are proposed based on the design criterion of Wald test both in the homogeneous environment and partially homogeneous environment. The proposed detectors are proved to be effective for suppressing the target-induced interference and they can ensure the desirable Constant False Alarm Rate (CFAR) property with respect to the unknown parameters of the noise. Simulation results show that the proposed detectors can suppress the interference effectively when the interference subspace is known, and can suppress the interference lying in the orthogonal complement space of the nominal signal subspace when the interference is completely unknown.
