摘要： In a radar system for monitoring targets in different distance ranges, radar pulses are emitted whose length is greater than the length corresponding to the propagation time between two objects to be distinguished from one another, located at different distances. On the receive side the high-frequency signal supplied to the radar transmit pulse former and the radar receive signal are supplied to a mixer. The output signal of the mixer is supplied to a signal analyzer via at least one sampler, whose delay setting with respect to the rising edge of the radar transmit pulse predefines the limit of reach of the distance range to be monitored.
