Abstract
A target detection and/or high resolution RF system is provided herein in which the resolution of a legacy target angle detection (direction of arrival) system is improved without any change to the existing hardware of the legacy target detection system. Rather, the target detection and/or high resolution RF system can apply virtual aperture postprocessing to reflected signals to achieve improvements in the detection of one or more targets.
Claims1
A target detection system, the system comprising:
- a signal generator configured to generate a waveform;
- a transmitter configured to transmit the waveform via an antenna;
- a receiver configured to receive a reflected waveform, wherein the reflected waveform comprises a version of the waveform that reflected off a target;
- a processor in communication with the receiver and configured with specific computer-executable instructions to:
- determine a real sensor spectrum using the reflected waveform;
- estimate a preliminary angle of the target based on the real sensor spectrum;
- predict intermediate virtual sensor data for the target based on the estimated preliminary angle;
- determine a virtual sensor spectrum using the predicted intermediate virtual sensor data;
- and
- combine the real sensor spectrum and the virtual sensor spectrum to form a beamformer output;
- and
- a display device configured to display a graphical representation of the beamformer output in a user interface.
