单脉冲雷达测角特性分析

Analysis of Angle Estimation in Monopulse Radar

研究单脉冲雷达幅相不平衡、馈源间距不为零等因素对比幅单脉冲测角的影响,仿真结果显示,幅度不平衡将会引起零位偏移,相位不平衡会导致测向灵敏度下降,而馈源间距对测角影响很小。

In this paper, the authors discuss the effects of amplitude-phase unbalance, nonzero distance between primary feeds on angle estimation characteristic of amplitude comparison mono-pulse radar. The simulation results show that amplitude unbalance will cause zero-offset, and phase unbalance will deteriorate the sensitivity of angle estimation, while the distance between primary feeds has little effects on angle estimation.
