| 摘 要： | 讨论了自适应对消实现扩频抗窄带干扰的基本原理,并进行了仿真实验,得出了采用干扰跟踪器来提高对消效果的结论.在航天704所开发的扩频应答机样机上进行了抗窄带干扰实验,结果表明：在扩频接收机中采用自适应对消器以及干扰检测和跟踪器后,至少可以做到43dB的抗窄带干扰能力.

| Abstract: | Adaptive noise canceling has been developed to eliminate narrow band jamming in a spread spectrum system. Simulation experiments show that a jamming tracker could improve the anti-jamming performance of a spread spectrum system. Experiments have also been carded out on the spread spectrum RSP developed by BRIT. The receiver achieves normal operation when J/S is 43 dB. |
