Patent ID: 7769105

Claim:
A method for transmitting low data rate symbols from a burst radar transceiver to a communications terminal, the symbols having information encoded therein, wherein the burst radar transceiver has a burst period including a burst interval and an inter-burst interval, the method comprising: dividing a symbol having a symbol period into a plurality of symbol sections, wherein each of the symbol sections has a symbol section interval that is less than or equal to the burst interval; modulating the symbol sections that occur during the burst interval onto a radar burst signal to form modulated radar bursts; transmitting the modulated radar bursts; discarding the symbol sections that occur during the inter-burst interval; receiving the modulated radar bursts at the communications terminal; accumulating symbol energy at the communications terminal from the modulated radar bursts to form an accumulated symbol energy; and identifying the information in the symbol based on a characteristic of the accumulated symbol energy.
