• The pseudorandom codes have a good autocorrelation of double - values . in recent years , to solve the problems of anti - interference and the ambiguity of range and velocity , a lot of countries do much research to change the waveform of radar signal . the most important improve is to use symmetrical pulses to interrupt frequency modulated continuous wave ( fmpcw )
  早期的fmicw采用伪码序列截断,伪随机码具有良好的双值自相关特性,其中最常用的是m序列截断的fmicw 。近年来,为了解决抗干扰和测距、测速模糊问题,许多国家已对雷达信号波形的改进进行了研究。
