ABSTRACT:
A pulsed RF oscillator employing a BIAS-ON path and a QUENCH path to produce fast turn-on and fast turn-off RF bursts with well-controlled burst width. The oscillator further includes amplitude and stability control elements, and a 5.8 GHz microstrip implementation is disclosed. The pulsed RF oscillator can be configured with quadrature RF homodyne detectors to form a range-gated pulse-Doppler motion sensor system for sensing target motion within a gated region. The sensor includes a transmitter for transmitting a sequence of RF bursts comprised of a number of cycles at the transmitter frequency. The sensor further includes a receiver responsive to the transmitted bursts and burst echoes from moving targets within its sensing field. The receiver produces Doppler signal with an amplitude representative sum of the transmitted burst and the echo burst. A Doppler motion response occurs for moving targets within a region sharply defined by the transmitted burst width. Another mode provides a quadrature receiver channel for target direction determination. Yet another mode time-sequences the transmitted burst widths to provide multiple range cell operation.
