Abstract: A method for remote object sensing on-board a vehicle includes employing compressive sensing to analyze a waveform originating from an on-vehicle low-resolution radar imaging system and reflected from a remote object. The compressive sensing includes generating a matrix including a temporal projection, a Fourier transform, and an integral term configured to analyze the reflected waveform. Leading and trailing edges of the remote object are identified by employing a norm minimization procedure to reconstruct a range profile based upon the reflected waveform analyzed by the compressive sensing.

Abstract: Systems and methods to perform sensor fusion with a depth imager and a radar system involve transmitting radio frequency (RF) energy from the radar system to a region and simultaneously emitting light to the region using a light source, Reflected light is received at a depth imager aligned with the light source, and RF reflections are received at the radar system. The reflected light is processed to obtain azimuth, elevation, range, variance in range, and reflectivity to each pixel that makes up the region. Processing the RF reflections provides azimuth, elevation, range, variance in range, velocity, and variance in velocity to a subset of the pixels representing a region of interest. Performing the sensor fusion includes using the azimuth, the elevation, the variance in range, and the reflectivity resulting from the depth imager and the range, the velocity, and the variance in velocity resulting from the radar system.

Abstract: A radar system includes antenna elements and receive channels. An adaptive switch couples the receive channels to a subset of the antenna elements as selected antenna elements. The selected antenna elements receive reflected signals from reflection by objects and each of the receive channels outputs the digital signal based on the reflected signal from the coupled selected antenna element. A controller processes the digital signal from each receive channel to estimate a direction of arrival (DOA) to each object and generate candidate configurations of the switch. Assessing the candidate configurations includes performing a multi-step assessment using a decision tree with each candidate configuration as a root and examining accuracy of an output at a last step in the decision tree to select a selected candidate configuration based on the accuracy. The switch is configured according to the selected candidate configuration prior to receiving the reflected signals for a next iteration.
