The present invention relates to a method of estimating a velocity magnitude of a moving target in a horizontal plane using radar signals received by a radar detection system, the radar detection system being configured to resolve multiple dominant points of reflection, i.e. to receive a plurality of radar signals from the moving target in a single measurement instance of a single, wherein each of the resolved points of reflection is described by data relating to a range, an azimuth angle and a raw range rate of the points of reflection in said single radar measurement instance. The invention further relates to a radar detection system.

Techniques for allowing a vehicle equipped with at least one radar to take-off and land using radar return images of a landing site. The at least one radar generates radar return image(s) of the landing site, specifically of reflective symbols attached to the landing site, allowing the vehicle to orient itself to the landing site and providing information specific to the landing site. Position and velocity in relation to a landing site can be determined using at least one radar and a guidance and landing system. Using the position and velocity information, the guidance and landing system can guide the vehicle to and from the landing site and/or determine whether an obstacle requires the use of an alternate landing site.

Embodiments are provided for managing the operation of sensors in an electronic device. According to certain aspects, the electronic device may detect a change in motion from a set of lower-sensitivity sensor data generated by a sensor(s) operating in a lower-sensitivity mode. When the change in motion is detected and during a timeout window, the sensor(s) may generate an additional set of lower-sensitivity sensor data and a set of higher-sensitivity sensor data. The electronic device may initially confirm the change in motion based on analyzing the set of higher-sensitivity sensor data. Further, the electronic device may determine that the additional set of lower-sensitivity does not indicate an additional change in motion, and may deem the confirmation of the change in motion as a false positive.

A computer includes a processor and a memory storing instructions executable by the processor to receive radar data from a radar sensor of a vehicle; demarcate a zone of coverage of the radar sensor, the zone of coverage having an area based on a number of objects indicated by the radar data; and after demarcating the zone of coverage, in response to detecting a newly present object in the zone of coverage, adjust a scanning rate of the radar sensor based on a distance of the newly present object from the radar sensor.

A hybrid radar system includes one or more low-frequency antennas configured to receive low-frequency reflected energy resulting from reflection of low-frequency transmissions, and one or more high-frequency antennas configured to receive high-frequency reflected energy resulting from reflection of high-frequency transmission. A frequency of the high-frequency transmissions is at least 1.5 times a frequency of the low-frequency transmissions. A processor obtains and processes one or more low-frequency digital signals resulting from the low-frequency reflected energy received at each of the one or more low-frequency antennas and one or more high-frequency digital signals resulting from the high-frequency reflected energy received at each of the one or more high-frequency antennas. The processor controls an operation of the vehicle based on information obtained by processing the low-frequency reflected energy and the high-frequency reflected energy.

Sensors, including radar sensors, may be used to detect objects in an environment. In an example, a vehicle may include multiple radar sensors that sense objects around the vehicle, e.g., so the vehicle can navigate relative to the objects. First radar data, e.g., from a first radar sensor, and second radar data, e.g., from a second radar sensor, can be analyzed to determine returns representing an object. The returns can then be used to determine a yaw rate and/or a two-dimensional velocity of the object. In some examples, differences in time between sensor data collection can be corrected/compensated based on previous (historical) tracked object information to provide better estimates.
