A Deception Jamming Strategy Against Target Parameter Estimation of Netted Radar
The enemy′s netted radar system often jointly estimates the parameters of the detected targets.In order to supress its parameter estimation performance, a deception jamming strategy against the enemy′s netted radar is proposed.Firstly, analysis is made to the principle of deception jamming against the enemy′s netted radar, which is conducted by an electronic jammer formation, and then the target′s echo signal model under the deception jamming is established.Based on this, the Fisher Information Matrix (FIM) of feature vector parameters of deception jamming is presented and then the estimation performance is analyzed.Finally, the sufficient condition of reaching the Cramer-Rao Lower Bound (CRLB) of the parameter to be estimated is derived, and a deception jamming strategy for supressing the parameter estimation performance of the enemy′s netted radar is given.Simulation results have proved the feasibility and validity of the proposed strategy.
