Since the video pulses come out in time sequence from one output port, when compared to a channelized receiver, less hardware is required in the parameter encoder. However, this hardware must operate at very high speed, equal to the bandwidth of the receiver. In most receivers, the input bandwidth equals the bandwidth of the dispersive delay line. Under this condition, if a receiver has an instantaneous bandwidth of 2 GHz, the logic circuit must also operate at 2 GHz. Each compressed pulse has a mainlobe with some sidelobes.

In general, the distribution of the spectrum is not needed. 4 Parameters in a radar pulse. signal, the information of interest is usually the starting and ending frequencies and the PW. The chirp is often assumed linear. The chirp rate Rc can be calculated by dividing the difference in frequency from the leading and trailing edges by the PW. 1) where // and / are the frequencies at the leading and trailing edges, respectively. In order to measure the frequency of a signal with variable frequency, theoretically, the concept of instantaneous frequency should be considered [29, 30].

2 lists the goals. The instantaneous bandwidth, the spatial coverage, and the number of simultaneous signals usually can be achieved if the receiver is so designed. The data length used for signal processing usually matches the minimum pulse width. This choice can provide the best signal-to-noise ratio [67].
