  • Patent number: H205
    Abstract: Improved signal to clutter response in a radar is achieved by transmitting broad bandwidth frequency modulated noise pulses. Utilization of millisecond pulse intervals enables the radar video processor to average the independent samples present in each echo pulse so that each pulse represents an estimate of the true average return from the background. The bandwidth of the IF processing circuit is equal to the RF circuit and transmitted pulse bandwidths.
