LFM-PC Hybrid Modulated Radar Signal Optimization Method Based on Alternating Direction Method of Multiplier
Aiming at the Doppler sensitivity problem of phase coded (PC) signals in the application of high-speed platforms and high-speed target detection, a wide Doppler tolerance signal based on hybrid modulation of Linear Frequency Modulation (LFM) and PC signals is studied. In this paper, the ambiguity function of the LFM-PC signal is derived, and the corresponding optimization model based on minimum integral normalized sidelobe level within the Doppler tolerance is established. A low-complexity signal optimization method based on alternating direction method of multiplier (ADMM) is proposed. The simulation results show that the optimized LFM-PC signal obtains the lower normalized sidelobe and extended Doppler tolerance.
