一、发展 SSR模式S的发展始于70年代初,英国和美国分别对SSR模式S进行开发。英国开发的这一系统称为选择地址(ADSEL)的SSR,而美国开发的系统称为离散地址信标系统(DABS),这两个系统在性能上有所不同。 1.英国的研制情况最初由RSRE(皇家信号和雷达委员会)代表CAA(民航局)进行开发,建立一个实验地面站和20个应答单元,对系统进行进一步研制开发,系统实验于1979年底完成并在来年进行了校验。可选择地址这一概念的可行性由英国进行校验并演示,确定了S模式系统的性能和最佳的运行规则,系统性能最重要的概念是测
First, the development of SSR mode S development began in the early 1970s, the United Kingdom and the United States were on the SSR mode S development. The system developed in the UK is called the SSR of ADSEL, and the system developed in the United States is called the discrete address beacon system (DABS), both of which have different performance. 1. Development in the United Kingdom Originally developed by RSRE (Royal Commission on Signal and Radar) on behalf of the CAA (Civil Aviation Authority), an experimental ground station and 20 response units were established to further develop the system and the system experiment was completed by the end of 1979 It was verified in the coming year. The feasibility of the concept of alternative addresses is verified and demonstrated by the UK to determine the performance and optimal operating rules of S-mode systems. The most important concept of system performance is to measure
