Radar and communication integrated systems have a promising perspective in the future. LFM-MSK, as one of the integrated waveform, has the same range resolution as the LFM waveform and same bit error rate as the MSK waveform. However, its phase continuous characteristic also brings about difficulties in velocity measurement for which an effective solution hasn’t been proposed yet. In this paper, the waveform formula for multi-target velocity measurement was deduced using coherent integration method. The uncertain phase in the formula which influences the velocity measurement is analysed and a method using self-multiplication is proposed to eliminate the phase and measure the target’s information through two spikes. The influence of the cross term between the targets is concluded into three cases. The detective probability of LFM-MSK is lower than LFM waveform because of energy split and a Monte Carlo experiment result under different signal to noise ratio is given. The simulation results show that the method can measure the velocities of multi-targets with favourable accuracy.
