摘　　要：本文首先推导得到大信噪比条件下单脉冲比的近似公式;然后根据和、差通道噪声特性求得单脉冲比的统计特性;最后利用极大似然估计原理推导单脉冲公式,同时得出了信噪比的极大似然估计。研究建立了单脉冲与极大似然估计的理论联系。该研究不仅有利于"雷达原理"课程教学,同时对雷达工程实践也有参考价值。At first, the monopulse ratio is approximated on the high SNR condition. Then the statistical property of monopulse ratio is obtained based on thermal noise in sum and difference channels. Finally, the monopulse formula is derived from maximum likelihood principle. Meanwhile, the SNR is estimated as byproduct. This work establishes a contact between monopulse and maximum likelihood principle. Both the teaching and radar engineering practice will benefit from this work.
