摘要
针对信号依赖干扰和加性背景噪声共同作用下的慢起伏静止延展目标探测问题,研究了信号混响噪声比(SCNR)准则下的波形优化设计算法。在能够准确获知干扰特性和目标特性的前提下,该自适应方法可有效提高输出SCNR。
Aiming at the problem that detecting stationary slowly fluctuating extended targets contaminated by signal-dependent interference and additive ambient noise,the optimal waveform design algorithms are investigated by the signal to clutter and noise ratio（SCNR）criterion.The adaptive method can effectively improve the output SCNR in the preconditions of knowing the exactly features of both interferences and target.
