Abstract:

Coherent repeater jammer (CRJ) may induce many false targets and degrade the true target detection performance. To deal with this problem, an adaptive transmit technique for antiCRJ is proposed. Firstly a burst of high repetition frequency pulse is transmitted to detect and estimate the paramters of CRJ. Then, based on the estimatesd parameters, the array transmit pattern is optimized to place nulls in the direction of jammer, therefore the probability of interception radar transmitted signal can be reduced. Numerical examples are provided to demonstrate the effectiveness of the proposed method.
