在孔径雷达和脉冲雷达中测量目标的距离

测量目标的距离是雷达的基本任务之一。无线电波在均匀介质中以固定的速度直线传播（在自由空间传播速度约等于光速 km/s）。图2-1雷达位于-Measuring the distance between the target is one of the fundamental tasks of radar. Radio waves in inhomogeneous media in a straight line to a fixed rate of propagation (the propaga

在发射端发射大时宽、带宽信号，以提高信号的速度测量精度和速度分辨力，而在接收端，将宽脉冲信号压缩为窄脉冲，以提高雷达对目标的距离分辨精度和距离分辨力。(In order to improve the speed measurement accuracy and speed resolution of the signal at the transmitter, the wide pulse signal is compressed into a narrow pulse at the recei
