Publication number: 20230333206Abstract: Disclosed herein are systems and methods for estimating target ranges, angles of arrival, and speed using optimization procedures. Target ranges are estimated by performing an optimization procedure to obtain a denoised signal, performing a correlation of a transmitted waveform and the denoised signal, and using a result of the correlation to determine an estimate of a distance between the sensor and at least one target. Target angles of arrival are estimated by determining ranges at which targets are located, and, for each range, constructing an array signal from samples of received echo signals, and using the array signal, performing another optimization procedure to estimate a respective angle of arrival for each target of the at least one target. Doppler shifts may also be estimated using another optimization procedure. Certain of the optimization procedures use atomic norm techniques.Type: ApplicationFiled: February 25, 2023Publication date: October 19, 2023Applicant: Neural Propulsion Systems, Inc.Inventors: Babak HASSIBI, Behrooz REZVANI

Publication number: 20230168359Abstract: Disclosed herein are systems, devices, and methods that may be used for autonomous driving and/or in autonomous vehicles. Some embodiments use an integrated wide-aperture multi-band radar subsystem and leverage the unique propagation properties of multiple bands and/or multiple sensor technologies to significantly improve detection and understanding of the scenery and, in particular, to see around corners to identify non-line-of-sight targets. In some embodiments, at least one processor of the system is capable of jointly processing return (reflected) signals in multiple bands to provide high accuracy in a variety of conditions (e.g., weather). The disclosed radar subsystem can be used alone or in conjunction with another sensing technology, such as, for example, LiDAR and/or cameras.Type: ApplicationFiled: January 27, 2023Publication date: June 1, 2023Applicant: Neural Propulsion Systems, Inc.Inventors: Behrooz REZVANI, Babak HASSIBI, Fredrik BRÄNNSTRÖM, Oguzhan TEKE
