Simulation and Analysis of ESB Algorithm Based on Frequency Diverse Array

The beam of phased array radar has angular resolution and no range resolution. The frequency diverse array adds a frequency increment which is much smaller than the carrier frequency between the array elements, thus forming a beam which is related to angle, range and time. On the basis of analyzing the characteristic of frequency diverse array beam, the mechanism of receiving only the transmitting array element frequency signal is introduced. The eigenspace-based beamforming algorithm is used to simulate the transmitting pattern, the receiving pattern and the dual path pattern, and the simulation results are analyzed. The performance of SINR under the ESB algorithm is simulated and analyzed. The results verify the effectiveness of the application of the ESB algorithm in the frequency diverse array. (paper)
