1. A target detection system, the system comprising:
a transmitter configured to transmit a waveform via an antenna;
a receiver configured to receive a reflected waveform in response to the waveform reflecting 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 first angle of the target based on the real sensor spectrum;
predict intermediate sensor data corresponding to a second receiver absent from the target detection system for the target based on the estimated first angle;
determine a virtual sensor spectrum using the predicted intermediate sensor data;
combine the real sensor spectrum and the virtual sensor spectrum to form a displayable output.
