  • Patent number: 10436895
    Abstract: An efficient RADAR imaging method that is able to detect an object within an interested area. This method uses electromagnetic waves transmitted by one or many transmitters to illuminate the interested area, and then estimates the phase shift of the scattered wave of an object according to the path that the electromagnetic wave propagated. By reversing the phase of the obtained scattered signal to the transmitters' position, an image is constructed for the entire interested area according to the correlation of signals in all channels. The present method works in the frequency domain. It produces a microwave image by using the phase and magnitude of the obtained signal, or using the phase information only. Other unique features include the way it synthesizes the signals obtained in multiple channels and at multiple frequencies. Its overwhelming high efficiency makes rapid microwave imaging and real-time imaging possible.

  • Patent number: 10401490
    Abstract: This document describes apparatuses and techniques for radar-enabled sensor fusion. In some aspects, a radar field is provided and reflection signals that correspond to a target in the radar field are received. The reflection signals are transformed to provide radar data, from which a radar feature indicating a physical characteristic of the target is extracted. Based on the radar features, a sensor is activated to provide supplemental sensor data associated with the physical characteristic. The radar feature is then augmented with the supplemental sensor data to enhance the radar feature, such as by increasing an accuracy or resolution of the radar feature. By so doing, performance of sensor-based applications, which rely on the enhanced radar features, can be improved.
