Systems, methods, and computer-readable media are described for compact radar systems. In some examples, a compact radar system can include a first set of transmit antennas, a second set of receive antennas, one or more processors, and at least one computer-readable storage medium storing computer-executable instructions which, when executed by the one or more processors, cause the radar system to coordinate digital beam steering of the first set of transmit antennas and the second set of receive antennas, and coordinate digital beam forming with one or more of the second set of receive antennas to detect one or more objects within a distance of the radar system.

A radar mounting structure includes: a corner upper beam; a lamp housing that houses a light source inside and that is attached to a vehicle-body upper side of the corner upper beam; and a radar configured to detect an object that is present ahead on a vehicle width direction outer side of a vehicle. The radar is disposed in front of the lamp housing so as to overlap with the lamp housing when viewed in a front-rear direction, and is fixed to the corner upper beam.

Various technologies described herein pertain to a sensor for an autonomous vehicle that includes one or more heat dissipation features. A sensor includes a top cover and a bottom cover, where the top cover and the bottom cover form at least a portion of a casing of the sensor. The sensor includes a coldplate, a first printed circuit board, and a second printed circuit board. A top side of the first printed circuit board is coupled to the top cover and a bottom side of the first printed circuit board is coupled to a top side of the coldplate. A top side of the second printed circuit board is coupled to a bottom side of the coldplate and a bottom side of the second printed circuit board is coupled to the bottom cover. Various features described herein enhance heat transfer from components on the first and second printed circuit boards.

The present embodiments relate to a radar coupler and a method for assembling the same. More specifically, there may be provided a radar coupler and a method for assembling the same, which may prevent a radar housing from escaping off a bracket when the bracket and the radar housing are simultaneously fastened together through a coupling part provided in the radar housing without using a socket, thereby preventing quality degradation that would arise if a socket is used and saving manufacturing costs.

A radar mounting structure includes: a first light source; a second light source; a first light source lens covering the first light source; a second light source lens covering the second light source; a first housing that houses the first light source inside; a second housing that houses the second light source inside; and a radar configured to detect an object present ahead on a vehicle width direction outer side of a vehicle. The radar is attached to the first housing and is covered by the second light source lens.

A system for scanning targets for concealed objects comprises a set of analog imaging components of a portable radar system with both a ranging resolution and lateral resolution sufficient to detect an object concealed on a person, where the analog imaging components are contained with a first housing and in communication with digital processing components contained in a second housing, where the digital processing components are configured to receive imaging information from the analog components for processing. Each housing is configured to be attached to a user's article of equipment.

Waveguide and/or antenna assemblies for RADAR sensor assemblies/modules, particularly those for vehicles. In some embodiments, the assembly may comprise a waveguide block defining one or more waveguides, each waveguide defined by a waveguide groove. In some embodiments, at least a portion of at least one waveguide groove is non-straight, such as meandering/oscillating back and forth. An antenna structure may be operably coupled with the one or more waveguides, which structure may comprise an array of one or more slots. In some embodiments, a single, elongated slot of the one or more slots may extend along an axis of each waveguide groove for delivering electromagnetic radiation from a corresponding waveguide of the one or more waveguides therethrough.

A sensor assembly includes a sensor and a cover disposed adjacent to the sensor to protect the sensor. The cover has an inner cover surface and an outer cover surface opposite the inner cover surface. The inner cover surface faces the sensor, and the outer cover surface faces away from the sensor. The cover has a first end wall and a second end wall apart from the first end wall along a first direction. The sensor assembly includes a cleaning system having a wiper movable along the outer cover surface of the cover in the first direction to clean to the outer cover surface. The wiper is at least partly made of a wiper material, and the wiper material includes a hydrophilic material to facilitate removal of water from the outer cover surface of the cover.

A sensor-cluster apparatus includes: sensors configured to detect and collect external environment information, the sensors including one or more kinds of sensors; a body member having one surface onto which the sensors are mounted; a case on which the body member is fixed, the case including: an inner space in which the body member is mounted; and an opening defined in one surface thereof exposing the inner space, the sensors are exposed through the opening; and a cover configured to open and close the opening of the case, wherein, the sensors are configured to be detached from the body member through the opening of the case with the body member fixed to the case.

A sensor apparatus includes a cylindrical sensor window defining an axis oriented substantially vertically, an air nozzle positioned below the sensor window and aimed upward, and a sensor-housing-top cap positioned above the sensor window and including a sensor-housing top and a circumferential cap. The sensor-housing-top cap is a single piece. The circumferential cap includes a topside and an underside. The topside and the underside are disposed radially outward from the sensor window. The underside includes a groove having a cross-section elongated circumferentially around the axis. The cross-section of the groove curves from a lower end upwardly and outwardly to an upper end.
