Abstract
The present invention is an integrated monitoring and communication receiver architecture. A staring receiver in accordance with the present invention may include a RF front end and a memory for storage of channel samples. The staring receiver may be capable of staring across an entire hopped communications bandwidth and storing a time-duration of channel samples within the memory to enhance acquisition and demodulation processing. The staring receiver may provide simultaneous visibility and reception of multiple signals with different time and frequency hopping patterns. Additionally, the staring receiver may be capable of spoofing whereby false cross correlations are presented to thwart geographically diverse intercept receivers.
Claims14
A method, comprising:
- capturing signals present in a radio frequency environment;
- embedding data within captured signals to create a follower jammer signal for each captured signal, said data including time stamp information and position information;
- transmitting the follower jammer signal with the embedded data at a frequency in which each captured signal of the capture signals was acquired;
- and
- re-transmitting said follower jammer signal at said frequency in which each captured signal of the capture signals was acquired, said follower jammer signal being re-transmitted after a delay of time after said follower jammer signal is first transmitted, the follower jammer signal creating false correlation peaks based upon a time distance of arrival information and a frequency distance of arrival information of said captured signals in a complex ambiguity function space from the embedded data within the follower jammer signal to prevent detection of said captured signal.
A system, comprising:
- means for capturing signals present in a radio frequency environment;
- means for embedding data within captured signals to create a follower jammer signal for each captured signal, said data including time stamp information and position information;
- means for transmitting the follower jammer signal with the embedded data at a frequency in which each captured signal of the capture signals was acquired;
- and
- means for re-transmitting said follower jammer signal with the embedded data at said frequency in which each captured signal of the capture signals was acquired, said follower jammer signal being re-transmitted after a delay of time after said follower jammer signal is first transmitted, the follower jammer signal creating false correlation peaks based upon a time distance of arrival information and a frequency distance of arrival information of said captured signals in a complex ambiguity function space from the embedded data within the follower jammer signal to prevent detection of said captured signal.
