A system for distributed dual-function radar-communication comprises a plurality of dual-function radar transmitters positioned within a region of interest, each configured to transmit at least one radar waveform, with each transmitter for having a minimum transmit power, a maximum transmit power, and a working transmit power, a plurality of radar receivers positioned within the region of interest, each configured to receive the radar waveforms, at least one controller communicatively connected to at least one connected transmitter of the plurality of dual-function radar transmitters, configured to calculate a vector of transmit power values for the plurality of dual-function radar transmitters. A method of transmitting a radar waveform is also disclosed.

System and method for distributed dual-function radar-communication

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 &#x3d5;, 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.
