Abstract

The phase array radar has been widely used in military due to the dramatic advance in computer technique and signal processing technology. In the meantime, the electromagnetic environment becomes more and more complicated. The phase array radar should have the ability to survive in the complicated electromagnetic environment. Therefore, the phase array radar should have good antenna pattern. The antenna pattern needs to maintain good performance at the pitch and azimuth for the sum beam and differential beam. In this paper, we propose the coefficient weights method to obtain the multi-objective optimization for the pitch and azimuth for the sum beam and differential beam. In addition, the adaptive interference suppression is another important part of the phase array radar. The proposed method in the paper also take this into consideration. Moreover, the paper gives sufficient validation results to show that the proposed method has good performance.
