Patent ID: 11852747

Abstract:
A novel and useful system and method for eliminating settling time delays in a radar system. In one embodiment, a plurality of oscillators is provided with a single transmitter. In an alternative embodiment, a plurality of transmitters is provided, each with its own oscillator. In either case, more than a single oscillator is used, whereby startup or turn on transients associated with one oscillator are allowed to settle out while another oscillator is being used. The two or more oscillators switch off and/or alternate or rotate such that oscillator settling time between chirp transmissions from the radar is substantially or completely eliminated. In a radar system having two transmitters, when the chirp propagation time window for the first transmitter is complete, the first transmitter is disconnected from the receive channel and the second transmitter is connected to the antenna and receive channel without having to wait for the second transmitter to settle since it was allowed to settle beforehand.
