Sorties Determination for Targets with Non-rigid-structure via Narrowband Coherent Radar

The sorties determination principle is discussed for narrowband coherent radar targets with non-rigid-structure based on a long coherent integration time in this paper.Firstly a novel signal model is proposed and some new concepts are put forward,such as common rotation Doppler,radial Doppler,chirp Doppler.And then it is pointed out that the initial frequency of target time-frequency distribution is decided by the sum of common rotation Doppler and radial Doppler,the trend is decided by chirp Doppler.Accord...
