Abstract

Transmitting beampattern synthesis is of great importance in colocated MIMO radar since the system demands a flexible power transmitting. However, most research focuses on the optimization of transmitting waveform covariance matrix and the design of transmitting waveform with the requirement of arbitrary waveform generators. In this paper, a transmitting beampattern synthesis method based on pulse-to-pulse coding is proposed. The waveform diversity is obtained in Doppler domain since each transmitting signal is modulated to a different Doppler frequency. Then by selecting the additional phase properly, the transmitting beampattern is synthesized to emit power to specific region. This proposed method could reduce the cost of system hardware since all transmitting signals are identical except the phase. Comparing to conventional transmitting beampattern synthesis method, the system complexity and computation complexity are reduced. Simulation results verify the efficiency of our proposed method.
