Open loop power oscillator Doppler radar

摘要

Described are radar systems and methods. A transmit pulse is generated by the radar system. A first portion of the transmit pulse is processed by the radar system to form transmit pulse data. A second portion of the transmit pulse is directed by the radar system into a monitored volume. A return signal is received by the radar system, the return signal at least partially comprising a portion of the second portion of the transmit pulse reflected by one or more objects in the monitored volume. The return signal is processed, by the radar system, to form return signal data.

1. A method performed by a Doppler radar system comprising:
generating, by the radar system, a transmit pulse; processing, by the radar system, a first portion of the transmit pulse to form transmit pulse data; directing, by the radar system, a second portion of the transmit pulse into a monitored volume; receiving, by the radar system, a return signal, the return signal at least partially comprising a portion of the second portion of the transmit pulse reflected by one or more objects in the monitored volume; tuning a local oscillator based on one or more frequencies of the transmit pulse; and processing, by the radar system, the return signal to form return signal data wherein the processing comprises down converting the return signal based on a signal from the local oscillator to form an intermediate frequency signal, wherein the signal from the local oscillator is calculated based on the transmit pulse.
