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