摘　　要：阐述低频化成为机载无源探测系统的发展趋势,机体对机载低频段天线方向图的影响,经对比分析,和差波束与干涉仪测向误差较小,适用于机载低频段天线高精度测向。This paper expounds that low frequency has become the development trend of airborne passive detection system, and the influence of the body on the pattern of airborne low-frequency antenna. Through comparative analysis, the sum and difference beam and interferometer direction finding error are small, which is suitable for high-precision direction finding of airborne low-frequency antenna.
