Abstract
A radar system mounted on a platform includes a transmitter turned off during a silent interval, and a receiver to receive one or more signals resulting from transmission by one or more other radars that transmit linear frequency modulated signals during the silent interval. A processor estimates parameters of the one or more other radars. The parameters include bandwidth and slope of the respective linear frequency modulated signal and the parameters are used to modify a transmitted signal or the processing by the radar system.
Claims10
A radar system mounted on a platform, comprising:
- a transmitter configured to be turned off during a silent interval;
- a receiver configured to receive one or more signals resulting from transmission by one or more other radars that transmit linear frequency modulated signals during the silent interval;
- and
- a processor configured to estimate parameters of the one or more other radars, wherein the parameters include bandwidth and slope of the respective linear frequency modulated signal and the parameters are used to modify a transmitted signal or the processing by the radar system, and the processor is configured to process subsequent signals resulting from subsequent transmission by the one or more other radars based on the parameters to perform detection.
A method of operating a radar system mounted on a platform, the method comprising:
- turning off a transmit portion of the radar system during a silent interval;
- receiving one or more signals resulting from transmission by one or more other radars that transmit linear frequency modulated signals during the silent interval;
- estimating parameters of the one or more other radars, wherein the parameters include bandwidth and slope of the respective linear frequency modulated signals;
- and
- modifying a transmitted signal or the processing by the radar system based on the parameters, wherein the modifying the processing includes receiving subsequent signals from subsequent transmission by the one or more other radars based on the parameters and performing detection.
