摘　　要：由于大气波导的抬升作用,电磁波会出现异常传播现象,导致雷达杂波明显增强。为了解决这一问题,本文提出雷达发射信号形式采用优选随机码,并结合码型捷变、硬限幅处理和优化动目标处理等信号处理方法有效抑制雷达杂波,提高雷达检测性能,并实际验证了此方法的有效性。Due to the elevated atmospheric duct, the electromagnetic waves transmit abnormally, which can strengthen radar clutters obviously. In view of this, the transmitting signals adopt the opti- mal random codes, combined with such signal processing methods as the code agility, hard limiter processing, and optimized MTI processing, to effectively suppress radar clutters and improve radar detection performance, verifying the effectiveness of the method.
