Angle Estimation of Two Targets in the Same Antenna Beam Using Adaptive Phase-Comparison Monopulse Technique Lee, Seong-Hyeon; Lee, Seung-Jae; Choi, Gak-Gyu; Yi, Jae-Woong; Kim, Kyung-Tae;
In this paper, we introduce an adaptive phase-comparison monopulse technique for angle estimation of two targets in the same antenna beam. The proposed method determines a more suitable technique(between conventional phase comparison monopulse technique and Zheng's method) based on interference between two targets in Fourier domain. Consequently, regardless of the interference, angles of each individual target can be accurately estimated by means of the proposed method. In simulations, we assumed that two point targets with same velocity are located in the same antenna beam, and the accuracy improvement of the proposed method is verified by using several simulations.
