针对复杂信号环境中非合作信号的电子侦察，为了提高信号的探测性能，提出了一种自适应干扰对消方法。该方法基于FPGA和DSP相结合的数字信号处理系统，通过时序控制、乒乓缓存方式和近实时的对消处理，可以适应干扰环境变化。通过器件校验，验证了该方法的有效性。

In view of the electronic reconnaissance of non-cooperation signals under the complex signal environment, this paper puts forward a method for adaptive interference cancellation, to improve the detection performance of the signals. Based on a DSP system that is combined with FPGA, this method can be adaptive to the changing of surroundings by ways of sequential control and ping-pang cache, and near real-time cancellation processing. By testing the devices, it is verified that this proposed method is of effectiveness.
