Abstract: A sensor module configured to be located behind a window of a vehicle to detect an object through the window and about the vehicle. The module includes a radar unit with an antenna and a controller. The antenna emits and/or receives a radar signal through the window with a selected or preferred polarization. The polarization determines a preferred angle of propagation of the radar signal through the window based on reflection characteristics of the window that vary with impingement angle and transmitted polarization. By varying the transmitted polarization vs. beam direction when a directional antenna is used, the signal propagating through the windshield can be maximized to enhance object detection over a range of signal directions. Also, by varying the transmitted polarization when an omnidirectional type antenna is used, the object can be ‘illuminated’ with variable intensity and detected with variable sensitivity.

Abstract: A Pseudo-Random Phase Modulation (PRPM) multiple-input-multiple-output (MIMO) radar system suitable for use on an automated vehicle includes a first transmit-antenna that transmits a first transmit-signal generated by a first PRPM-code, a second transmit-antenna that transmits a second transmit-signal generated by a second PRPM-code, a receive-antenna used to detect a first reflected-signal arising from the first transmit-signal and a second reflected-signal arising from the second transmit-signal, and a controller. The controller is in communication with the receive-antenna and is operable to generate the first PRPM-code and the second PRPM-code. The controller is configured to generate a first sub-channel-output based on a down-converted-signal from the receive-antenna and the first PRPM-code, generate a second sub-channel-output based on the down-converted-signal from the receive-antenna and the second PRPM-code, determine a first residue-signal based on the second sub-channel-output, and determine a first residue-removed-signal by subtracting the first residue-signal from the first sub-channel-output.

Abstract: A bi-static radar system configured for coherent detection of a radar-signal includes a plurality of radar-transceivers, a controller, and a communications device. The plurality of radar-transceivers is characterized as physically spaced apart with respect to each other. The controller is in communication with the each of the radar-transceivers and is configured to coherently operate each of the radar-transceivers. The communications device communicates both a reference-clock signal and a frame-sync signal from the controller to each of the plurality of radar-transceivers whereby the plurality of radar-transceivers operate coherently. Alternatively, the system may include a reference-signal generator, a transmitter, and a plurality of receivers. The reference-signal generator generates a reference-signal characterized by a reference-frequency proportional to a fraction of a radar-frequency of a radar-signal transmitted. The transmitter generates the radar-signal at the radar-frequency based on the reference-signal. The plurality of receivers operates coherently to detect the radar-signal based on the reference-signal.

Abstract: A radar system includes a controller equipped with memory for storing data. The controller is configured to receive a time-domain signal representative of a reflected signal detected by an antenna, and transform the time-domain signal into a plurality of range datasets. Each range dataset corresponds to one of the plurality of chirps, each range dataset is represented by a series of values assigned to a plurality of range bins, and each of the values includes a sign bit. The controller is also configured to compress the plurality of range datasets by storing in the memory a portion of each of the values assigned to at least one of the plurality of range bins, wherein the portion is defined to exclude a first number of redundant sign bits of each value. The controller may further compress the portion by retaining a second number of bits of the data by excluding some of the least significant bits of each value.
