Patent ID: 7952515

Claim:
A range-gated holographic radar, comprising: a PRI generator for producing PRI pulses; an intermediate frequency IF generator for producing an IF modulation signal; a stagger modulator responsive to the PRI pulses and to the IF modulation signal for producing staggered PRI pulses; a first pulse generator responsive to the staggered PRI pulses for generating transmit pulses having a duration longer than the longest transmit pulse to desired echo duration; an RF oscillator responsive to the transmit pulses for producing transmit RF bursts and for forming reference waves; an antenna connected to the RF oscillator for radiating the transmit RF bursts and for receiving echoes from the bursts; a range delay element connected to the PRI generator for producing range delay pulses; a second pulse generator responsive to the range delay pulses for generating gate pulses; an RF magnitude sampler responsive to the gate pulses and connected to the antenna for producing RF magnitude samples of the sum of the reference waves and echoes; an IF bandpass filter for passing IF modulated magnitude samples; and an IF detector for demodulating the filtered magnitude samples and for producing an interferometric output signal.
