Velocity Ambiguity Resolution and Synthesis Processing in Multi-frequency MIMO Radar
|
Abstract:
The multi-frequency MIMO radar uses sparse-array to transmit the FMCW signals of multiple carrier frequencies,and an array to receive the echoes.The signal model of multi-frequency MIMO radar is analyzed in this paper.A new method is proposed to resolve velocity ambiguity,using which the least squared estimation of real velocity can be obtained from the ambiguous Doppler shifts corresponding to the different transmit frequencies without transmitting multiple PRF(Pulse Repetition Frequency) signals.Another m...
