| 1. | Then to meet the problem of the separate between receiving and transmitting for single - station radar system in continuous wave principle , we introduced frequency modulated interrupted continuous wave ( fmicw ) . in early days , the pseudorandom codes were often used in fmicw . usually m - sequence is used to intertupt frequency modulated continuous wave 之后,为了解决连续波体制下,单站收发共址的雷达系统的收发隔离问题,又普遍采用了截断的线性调频连续波信号形式,叫做线性调频中断连续波信号( fmicw ) 。 |
