Abstract

A new combined radar signal-pseudo-random binary-phase code phase modulation and LFM combined radar signal is proposed, and the frequency spectrum function, the ambiguity function and the range correlation function are deduced. The working principle of combined radar is illustrated in detail and the formula of signals in each stage is deduced and the Doppler signal and it´s effect on the correlation output of radar system is analyzed. Finally, the resolution, ambiguity characteristics and the range cut-off characteristic are studied. Research shows that the new combined radar system is feasible and has advantageous performance
