| description | Direction of arrival estimation is one of the key technologies in automotive radar system. The angular resolution is an important indicator for evaluating the radar performance. Here, an optimisation method of linear antenna array configuration used for automotive radar system is presented. The array is composed of three transmitters and four receiver (3T4R). By minimising the strong correlation region of the ambiguity function using genetic algorithm. A desired angular resolution is achieved under several certain constraints. Simulation results demonstrate the validity of proposed method. |
