前言本发明研究与雷达特征检测和分析的瞬时测频(IFM)接收机一同使用的一种设备。该设备克服了在下述情况下出现的数据处理问题,即有两个不同频率的射频(RF)脉冲存在,在第一个脉冲频率被完全编码之前的某个时刻接收到了第二个RF脉冲。当所接收的这两个RF脉冲的前沿相隔的时间大于接收机视
Introduction The present invention investigates an apparatus for use with an instantaneous frequency measurement (IFM) receiver for radar signature detection and analysis. This device overcomes the data handling issues that occur when two radio frequency (RF) pulses of different frequencies exist and receive a second RF pulse sometime before the first pulse frequency is completely encoded. When the leading edge of the two received RF pulses are separated by more than the receiver view
