A Method of Synthesizing Range Profile Based on LFM -BPSK Signal

In allusion to the design of a sharing signal for radar imaging and communication in integrated radar and communicationsystem, a general design mode is analyzed for integrated signal. First, an integrated radar and communication signal is designedbased on LFM-BPSK modulation, which can transmit with communication information phase modulation. The expression is givenfor the echo signal from an extended target. Secondly, by way of computing inverse discrete Fourier transform or discrete Fouriertransform of echo signal sample, a method of synthesizing range profile is proposed based on integrated signal. Then, according tothe effect of phase factor on fourier transform, the influence of Doppler effect on synthesizing range profile is analyzed for the newintegration signal. Finally, some simulation is provided for verified the theoretic analysis in radar imaging performance of the newsignal.
