Abstract: A distance measuring device is configured to emit a transmitted wave and detect a reflected wave from an object irradiated with the transmitted wave to measure a distance to the object. At least one of the transmitted wave and the reflected wave is transmitted through a transmission window. A heater is configured to heat the transmission window from an inside of the distance measuring device. A control unit is configured to control energization of the heater according to an inside air temperature which is an air temperature inside the distance measuring device and an outside air temperature which is an air temperature outside the distance measuring device.

Abstract: A sensor assembly for detecting an object and a method of forming a sensor port in sheet metal are disclosed. The sensor assembly includes at least one electromagnetic source for emitting electromagnetic waves. The sensor assembly also includes at least one electromagnetic receiver for receiving the electromagnetic waves after reflecting from the object and corresponding with a detection of the object in proximity to the sensor assembly. In addition, the sensor assembly includes a filter cover disposed adjacent to and covering the at least one electromagnetic source and the at least one electromagnetic receiver configured to allow the electromagnetic waves to pass therethrough while reflecting visible light, thereby concealing the at least one electromagnetic source and the at least one electromagnetic receiver.

Abstract: An electronic device includes a transmission antenna that transmits a transmission wave, a reception antenna that receives a reflected wave that is the transmission wave having been reflected, and a control unit that detects a target by using a constant false alarm rate, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave. The control unit sets a test region and at least one or more reference regions with respect to the test region in a distribution of signal intensities based on the reception signal in a distance direction, and sets a threshold for use in detection of the target, based on an order statistic among signal intensities in the reference regions.

Abstract: This axial deviation estimating device estimates an axial deviation angle of a radar device mounted on a mobile body, and includes an acquiring unit, an extracting unit, a device-system coordinates unit, and an estimating unit. The estimating unit estimates an axial deviation angle using a relational expression. The relational expression is an expression that holds between at least one unknown parameter, which includes an axial deviation angle of a coordinate axis of the radar device about a target axis which is at least one of a horizontal axis and a traveling direction axis constituting the coordinate axes of the mobile body, and at least one element included in the device-system coordinates of a road surface reflection point.

Abstract: A target detecting apparatus based on radar includes a radar sensor that radiates radar signals in different directions of a vehicle to detect a target, and a controller that generates an initial track based on target detection information from the radar sensor, and compares first detection sensor information obtained by detecting the initial track and second detection sensor information, in which a location coordinate of the initial track is included in a detection area, to determine whether the initial track is a false target.

Abstract: An axis deviation angle estimation device estimates a vertical axis deviation angle of a radar device based on roadside object information including information on a plurality of reflection points on a roadside object and road surface information including information on a plurality of reflection points on a road surface. The vertical axis deviation angle is an angle of deviation of an actual mounting direction from a reference mounting direction in a vertical direction. The actual mounting direction is an actual direction of the radar device, and the reference mounting direction is a direction of the radar device when the radar device is mounted in a reference state.
