摘要 提出一种基于Radon- STFT的DSSS系统线性调频干扰对消算法,仿真实验表明,该方法可以在较大的动态范围内有效地抑制线性调频干扰。与基于STFT的抑制算法相比,其参数估计精度大大提高;与基于WHT的抑制算法相比,该方法在多分量条件下效果更为突出,其运算量也显著降低。 This paper proposes a LFM interference suppression method in direct sequence spread spectrum (DSSS) receiver based on Radon-STFT. Performance analysis and simulation results have showed that the proposed method works effectively in a large dynamic range. Compared with the STFT based algorithm, it is accurate. Compared with WHT based algorithm, it is better in conditions of multi-component LFM interferences and easy in computation.
