Abstract: The present disclosure relates to a method and system in a wireless network for radar detection in certain bands e.g. bands normally used for unlicensed access. In one broad aspect, a method is provided for a network node configured to control wireless transmissions in a frequency band also used for radar transmissions.

The method includes after a wireless transmission during the transmit-on time of a first transmission cycle, detecting, during the transmit-off time of the first transmission cycle, at least one radar pulse in the frequency band and extending the transmit off time of a second transmission cycle based on the at least one radar pulse detected.

Abstract: A radar apparatus is attached to a vehicle such that a direction at 90 degrees relative to a front-rear direction of the vehicle is included in a detection range, and transmits and receives radar waves. The radar apparatus detects an observation point relative speed that is a relative speed in relation to an observation point that has reflected the radar wave within the detection range and an observation point azimuth that is an azimuth at which the observation point is present. The radar apparatus determines that a moving object is detected when an expression expressed by V<Vs·sin ((?-?) is satisfied, where ? is an attachment angle that is an angle at which a center axis of a reception antenna receiving the radar wave is angled in relation to a width direction of the vehicle, V is the observation point relative speed, ? is the observation point azimuth, and Vs is a traveling speed of the vehicle.

The altimeter can be configured to determine an altitude of the unmanned aerial vehicle above a target surface based on time of flight of radar pulses between the ultra-wideband radar antenna and the target surface.

Abstract: Described techniques and apparatuses relate to determining an attenuation environment surrounding a satellite terminal in a satellite communication system. The satellite terminal may receive signals from an auxiliary satellite system, and determine aspects of an attenuation environment that may affect communications with a communications satellite system.

Abstract: A radar apparatus includes a targeting unit that irradiates a radar wave and recognizes a detection subject using a reflected wave thereof. The targeting unit extracts, as a target, a peak that is confirmed to have historical connection over measurement cycles equal to or more than a predetermined targeting threshold, from peaks extracted from a power spectrum generated by frequency analysis. A rainy-weather determining unit determines that weather is rainy when a number of erroneous detections is greater than a predetermined rainy-weather determination threshold. The number of erroneous detections is a number of peaks that have been detected in a previous measurement cycle or earlier by the targeting unit and are not confirmed to have historical connection to a peak detected in a current measurement cycle.
