摘要
由于导弹在真实的飞行过程中相对地面运动,引起信号多普勒和时间延迟变化,而测控系统在进行地面联试过程中迫切希望能够模拟这些动态特性,以保证雷达在真实环境中能够正常工作;信道模拟器就是为实现这一目标而设计的,根据弹道信息利用模型计算模拟出信号的空间传输特性,制造出各种典型信道特性和电磁环境,模拟出终端信号的多径效应、噪声、距离延迟、多普勒信息,以实现测控系统的准动态联试;应用表明,该模拟器能够满足任务前的系统动态联试,还可用于雷达的日常维护训练。
The signal＇s Doppler and time-delay will be changed, when the missile flight in the sky opposite to the ground, The test command urgently simulate these dynamic characteristics in order to check the radar in the true test environment. For this purpose, we design the channel simulator, using the ballistic trajectory can compute and simulate spacial propagation characteristics, make the various typical channel characteristics and electromagnetism environment. The terminal can simulate multipath effect, Noise, Signal Delay, Doppler. To achieve a quasi-dynamic system integration and test. The application indicate the channel simulator can fulfill the requirement of test, also be used for the daily maintenance and training of radar.
