The analog signal styles include conventional pulses, frequency rapid change(pulse rapid change, Pulse rapid change), frequency diversity, Pulse compression(linear FM, nonlinear FM, phase encoding), variable frequency(heavy frequency jitter, heavy frequency parameter difference), phase encoding + frequency encoding, etc.. ::The scan angle can cover the azimuth ± 180 ° and pitch in the range of 0 ° ~ 90 °.
