Abstract
A method and apparatus for pulsed oscillator heterodyne detection is described and advantageously applied to pulsed Doppler radar systems. The pulsed Doppler radar system utilizes a modulation repetition frequency signal to independently generate phase-coherent pulse modulation of both a transmitted and a local oscillator signal. Since each of the signals are, independently, phase coherent with respect to the modulation signal, a heterodyning operation produces a stable baseband signal, useful for transmitted signal detection, processing and analysis. The method and apparatus is advantageously applied to bi-static and telemetry receiver arrangements, where now the local oscillator signal is generated from a received or detected modulation repetition frequency. The disclosed heterodyne detection system circumvents the need for more expensive, bulky high-frequency electronics, and represents a significant reduction in cost, complexity, size and weight of pulsed Doppler radar systems.
