  • Publication number: 20230366979
    Abstract: A communication system, method and computer program product enable transmitting information via the same spectrum as a multiple-input multiple-output (MIMO) radar using the same spectrum. First, a radar system conducts a search mode using a MIMO radar waveform. Second, an uplink communications transmitter employs a new type of signaling that allows the radar to search for targets in the spatial direction of the communication transmitter. Specifically, the MIMO radar can conduct a search task while receiving data from a communication transmitter using the same frequency allocation without blinding the MIMO radar in the direction of the target.

  • Patent number: 10725175
    Abstract: A receiver method and apparatus provides a more efficient computation and application of optimal filters. Range and Doppler processing in the receiver are decoupled and, as a result, computational complexity required for both filter computation and filtering stages are significantly reduced. In one embodiment, a response to an emitted signal is demodulated and sampled to provide baseband samples. The response includes a component due to interaction of the emitted signal with a target, The baseband samples are filtered in a bank of N parallel range filters to provide N filter outputs for each of the baseband samples. For one or more Doppler phase shifts ?, a discrete Fourier transform of the N filter outputs is computed to produce Doppler components that may be analyzed to determine at least one of a presence, range and speed of the target.
