摘要
提出了一种合成孔径雷达二维匹配噪声干扰的方法。首先介绍二维匹配噪声干扰的原理;其次通过与一维距离向噪声干扰对比,阐述了该方法在计算量和干扰能量上的优缺点;然后分析了测距和测速误差对信号处理增益的影响;最后通过仿真验证了理论分析的观点。仿真结果表明该方法原理正确,具有很好的干扰效果。
A method of two-dimensional matched noise jamming against synthetic aperture radar is proposed. First, the principle of the method is described. Second, comparison with one-dimensional noise jamming in range dimension, its advantages and disadvantages are given in terms of computational load and jamming energy. Third, the loss of signal processing gain is analyzed in terms of measuring errors in range and velocity. At last, simulation results are given. They indicate that the principle is correct and more effective than other noise jamming methods.
