1. pulse waveform that is used for scene surveillance radar;

  • It is characterized in that;

    Pulse waveform alternately is made up of a burst pulse and a broad pulse, and a pulse waveform cycle is made up of the burst pulse of one-period and the broad pulse of one-period, and burst pulse is made up of single carrier frequency sine wave signal;

    The pulsewidth τ

    1=10ns~

    100ns of burst pulse, the cycle T of burst pulse=40 μ

    s~

    400 μ

    s;

    Broad pulse is made up of linear FM signal, the pulsewidth τ

    2=1 μ

    s~

    20 μ

    s of broad pulse, and the bandwidth B=10MHz of broad pulse~

    100MHz, the cycle of broad pulse is T.
