Multi-carrier Frequency MIMO HF Radar Using Convex Optimization Beamforming

摘要：

In order to enhance HF radar angle resolution, and overcome target RCS scintillations, we adopt the transmitting and receiving antennas sparse deployment under bistatic pattern, the element intervals far less than range from the target to transmitters and receiver, the transmitters emit multi-carrier frequencies. In this paper, we apply CVX theory to solve the optimal weights of each element at different frequency, take advantage of multi-carrier frequency signal phase changing offset the side lobe each other. The beampattern has better angle resolution, and achieves lower side lobe. In the end, we analyze that the different frequency echo amplitude and phase impact side lobe and direction errors
