| 摘 要： | 针对自适应抗干扰技术展开研究,提出了易于FPGA实现的FFT自适应窄带抗干扰技术.这种方法减小了数字信号处理部分的计算量,提高了系统处理的实时性,降低了系统的复杂程度.实验表明在有宽带干扰存在的情况下,使用所提出的方法可以自适应检测并剔除窄带干扰.与GPS接收机的对接测试表明,该技术能大大提高接收机的抗干扰能力.

| Abstract: | The adaptive anti-jamming algorithm is researched in the paper, a FFT adaptive anti-jamming algorithm on FPGA is proposed. Due to the new method, the performance of the system is improved while the structure is simplified. Experiment indicates that when wideband interference exists, narrowband interference can be detected and eliminated using the proposed method. |
