【摘要】 针对机载防撞系统TCAS空对空通信时存在的同步混扰,给出了抑制干扰的问询功率控制方法。文中针对S模式目标和A/C模式目标分别提出了动态问询功率控制方法和可变步进的W/S呼叫序列的问询功率控制方法。建立了高密度空域中飞机的分布模型,据此分析了问询功率控制方法的有效性和实用性。此外,还给出了问询功率控制方法的实现流程及其在目标监视功能中的工程实现方式。
【Abstract】 The methods of controlling the transmit power of integration to limit the interferences which are resulted from air-to-air communication in the Traffic alert Collision Avoidance System are proposed.The dynamic controlling of tracking integration power for mode S targets and the variable steps Whisper/Shout interrogation for mode A/C targets are presented.In order to analyze the validity of the methods,the distribution model of aircraft traffic density is established.Additionally,the procedure for interrogations power controlling and the implementation in surveillance function are described.
