现代二次监视需达(SSR)采用单脉冲技术测量目标的方位位置。木文简要叙述了两种主要单脉冲接收机形式(幅度估计和相位估计)及其折衷选择的分析。在序言性的讨论了性能降低的主要原因之后,详细分析是以有关回答检测和编码确认的宴际现象的数学模型为基础进行的。数学模型用于塞莱尼亚公司的经考验过的单脉冲接收机,并以解析的形式和易于理解的图示给出了精度、分辨率、P_n和P_n的有关结果。二次监视雷达性能的实验鉴定以及同数学结果的比较将在会议上提供。
Modern Secondary Surveillance (SSR) uses a single pulse technique to measure the target’s azimuth. Mu Wen briefly describes the analysis of the two main types of monopulse receiver (amplitude and phase estimation) and their trade-offs. After prefacedly discussing the main causes of performance degradation, the detailed analysis was based on a mathematical model that answers the banquet-like phenomena of detection and coding validation. The mathematical model is used in Celestia’s proven monopulse receiver and gives results in terms of resolution, resolution, P_n and P_n in analytic form and easy-to-understand illustrations. Experimental identification of secondary surveillance radar performance and comparison with mathematical results will be provided at the conference.
