摘要：
Cross eye jamming is one of the most effective jamming methods for monopulse radar, and cross eye gain is an important index to measure the performance of cross eye jamming. Based on the gain models of two source retro-directive cross-eye jamming(TRCJ) and linear array multi-source retro-directive cross-eye jamming(LMRCJ), the maximum gain value of LMRCJ under the same amplitude ratio is deduced by taking the cross eye interference of 4-source linear array as an example, and the calculation method of overall phase tolerance of LMRCJ is proposed. Considering the phase control mode between different loops of LMRCJ, amplitude phase fluctuation and platform echo, the gain value and amplitude compatibility limit of LMRCJ and TRCJ are compared and analyzed. The simulation results show that, without considering the platform echo, the maximum gain of TRCJ is not lower than that of LMRCJ under the same amplitude ratio, and the phase tolerance of TRCJ is more relaxed than that of LMRCJ when the gain is high; when the amplitude and phase control capabilities of LMRCJ and TRCJ are the same and weak, the gain of LMRCJ is higher than that of TRCJ; when considering the platform echo, the gain and phase tolerance of LMRCJ and TRCJ are consistent with those of isolating platform echo at high JSR. The paper can provide guidance for the engineering design of the cross-eye jammer. © 2021, Chinese Institute of Electronics. All right reserved.
