在我所已生产的单脉冲雷达测速设备中,都有一个简单的模拟器,它能提供真实目标所具有的速度和加速度(它以对应的多卜勒频率及变化形式给出)。凭借测速回路对此信号的跟踪,可检查系统的正常与否,判断故障是产生在内部还是外部。由于以往的模拟器不能产生测速和测距相参的雷达回波信号,因此消除测速模糊的检查必须在多卜勒速度和加速度为零的特定条件下进行。这样又使模拟的真实程度受到 In my monopulse radar velocimetry equipment, there is a simple simulator that gives the true target velocity and acceleration (given by the corresponding Doppler frequencies and variations). With the speed loop tracking of this signal, the system can check the normal or not, to determine whether the fault is generated internally or externally. Since previous simulators were unable to generate radar echo signals with velocity and range coherence, the elimination of velocity blur checks must be performed under the specific conditions of Doppler velocity and zero acceleration. This in turn allows the true extent of the simulation to take place
