A distributed MIMO radar oriented barrage jamming strategy

Distributed multiple input multiple output (MIMO) radar has attracted much attention for its improved detection and estimation performance as well as enhanced Electronic Counter-Counter Measures (ECCM) ability. In order to protect the target from being detected and tracked by such radar, we consider a barrage jamming strategy orienting towards a distributed MIMO. We first derive the Cramer-Rao bound (CRB) of target parameters estimation using a distributed MIMO under barrage jamming environments. We then set maximizing the CRB as the criterion for jamming resource allocation, aiming at degrading the accuracy of target parameters estimation. Particle swarm optimization is utilized to solve the maximizing problem. Simulation results demonstrate the advantages of the the proposed strategy over traditional jamming methods.
