The characteristics and the principle of Multiple Carrier Frequency MIMO radar system are systemic introduced and the Frequency Modulated Continuous Wave (FMCW) signal and the return signal are analyzed.Then the processing of FMCW when the target is still or moving are detailed discussed as well as some key problem
e.g.the design of Channel Separation Filter (CSF)
the range resolution analysis
the precision analysis of velocity compensation and the decision of coherent integration number etc.Based on the characteristics of multiple carrier frequency
the method to employ the IFFT to coherently synthesize pulse is proposed to obtain High Range Resolution (HRR) and a scheme is put forward to solve the coupling of range and velocity when the target is moving and the simulation result shows that it is practical.
