The power supply of claim 1, further comprising: the waveform generator processing and combining a first signal having a sequence of non-inverted single-cycle sine waves and a second signal having a sequence of inverted single-cycle sine waves to generate the first alternating non-inverted/inverted raised cosine waveform and the second alternating non … 網頁In this paper, a low probability of intercepting radar waveform design method is proposed. The time-frequency image of the designed radar waveform is agile and random. Its time-frequency image is more complex than a chirp. This paper first determines the number of sub-pulses in a single pulse. Then find random points on the time-frequency plane of unit …
