System and method of controlling operation of an optical sensor in a device. The optical sensor is configured to employ a scan pattern to scan respective portions of a full field of view. A navigation sensor is configured to obtain location coordinates of the device. An inertial sensor is configured to obtain an acceleration data of the device in a plurality of directions. A controller is configured to determine a position of the device at the present time based in part on the location coordinates and the acceleration data. The controller is configured to determine a sun striking zone based in part on a relative position of the sun and the device. When a sun overlap region between the respective portions of the full field of view and sun striking zone exceeds a first overlap threshold, operation of the optical sensor is modified.

System and method of controlling operation of a device having an optical sensor

A vehicle, radar system for the vehicle and method for detecting an object. The radar system includes a transmitter for transmitting a source signal and a receiver for receiving a reflection of the source signal from an object. A processor obtains a radar parameter of the object from the received reflection, adjusts an operating parameter of the radar based on the radar parameter to provide an altered source signal, and detects the object based on a reflection of the altered source signal.

Sequential target parameter estimation for imaging radar

A vehicle and/or a method for detecting contaminants on an optical surface are provided. The vehicle includes at least one light source adjacent the optical surface and at least one light detector at an edge of the optical surface. A controller is configured to introduce light from at least one light source into the optical surface, and to measure light at the edge of the optical surface with at least one detector. The controller compares the measured light to a threshold, and, if the measured light crosses the threshold, triggers or implements a response action.

Optical surface contaminant detection

A radar circuit for use with a host system such as a vehicle includes a radio frequency (RF) signal generator configured to generate a predetermined RF waveform, an RF antenna connected to the RF signal generator, and an ECU which executes a method. As part of such a method, a signal generator transmits the RF waveform toward different radar target types, and receives return signatures reflected therefrom. The ECU receives the return signatures from the antenna, processes the return signatures via parallel constant false-alarm rate (CFAR) subdetectors each with defined cells under test to detect the target types as a set of detection events, merges the detection events into a merged set, and executes a control action aboard the host system responsive to the merged set. Each subdetector detects a corresponding one or more of the radar target types via corresponding detection parameters.
