引言采用连续波调制的跟踪系统已成功地应用于跟踪协同式飞行器。这就是在飞行器中装上应答器,接收测距信号,以某种方式处理后,再发射出去。目前使用的宇宙飞船跟踪、导航、空中交通管制之类的某些系统就是如此的。由于经典的雷达理论和设计是部分地以非协同式目标为前提的,因而并不特别适用。这方面的很多理论分析必然涉及到在存在噪声的情况下探测目标的问题。已有的大多数设计采用了脉冲调制技术。因为回
Introduction Tracking systems employing continuous-wave modulation have been successfully used in tracking cooperative aircraft. This is where the transponder is installed in the aircraft to receive the ranging signal, processed in some way and then transmitted. This is true for some systems such as spacecraft tracking, navigation and air traffic control currently in use. Since classical radar theory and design are partly based on non-collaborative goals, they are not particularly applicable. Much of the theoretical analysis in this area necessarily involves the question of detecting a target in the presence of noise. Most designs already use pulse modulation technology. Because back
