摘要： Aspects of this disclosure relate to controlling one or more vehicle systems based on a determined weather condition. In some embodiments, a radar system can be mounted on a vehicle and can collect weather data by receiving electromagnetic signals. A weather condition can be determined based on the collected weather data, and a vehicle system can be controlled based on the determined weather condition, such as vehicle lighting, windscreen wipers, or cruise control. In some embodiments, weather conditions can include fog, sleet, or smog. The weather condition can be determined by analyzing scattered reflections from incident microwaves and/or radio waves to determine a level of attenuation of the scattered electromagnetic energy indicative of a presence or absence of particles. A map can be displayed displaying the weather condition and controlling vehicle navigation systems. The collected weather data can be compared with data from a LiDAR or camera system for reliability.

摘要： A system and method for computing radar based precipitation estimates using inverse distance weighting is provided. In an embodiment, an agricultural intelligence computer system receives first electronic digital data comprising a first plurality of values representing precipitation gauge measurements at a plurality of gauge locations. The agricultural intelligence computer system obtains second electronic digital data comprising a second plurality of values representing radar based precipitation estimates at the plurality of gauge locations. For each radar based precipitation estimate value at the plurality of gauge locations, the agricultural intelligence computer identifies one or more corresponding precipitation gauge measurement values, computes a gauge radar differential value for the radar based precipitation estimate based, at least in part, on one or more corresponding precipitation gauge measurement values and the radar based precipitation estimate value, and stores the gauge radar differential value with location data identifying a corresponding location of the plurality of gauge locations. The agricultural intelligence computer system then obtains a particular radar based precipitation estimate at a non-gauge location. The agricultural intelligence computer system determines that one or more particular gauge radar differential values at one or more particular gauge locations correspond to the particular radar based precipitation estimate at the non-gauge location and computes a particular radar based precipitation estimate error at the non-gauge location based, at least in part, on the one or more particular gauge radar differential values at the one or more particular gauge locations and one or more distances between the non-gauge location and the one or more particular gauge locations.

摘要： A radar camera of a signalized traffic control system determines rain intensity, compares it to a threshold, then adjusts traffic signal operation. Rain intensity of a level relative to the threshold causes the traffic control system to operate in a rain intensity mode. The rain intensity mode has the system hold a call to a traffic light controller during the time when rain intensity is above the threshold. The traffic control system includes a radar camera, traffic controller, a computer with memory, and program instructions. A manner of operation includes sampling camera radar, counting the number of raindrops and raindrop size within a predetermined range, determining rain intensity using the measured raindrop parameters/characteristics, comparing the determined rain intensity with a rain intensity threshold, and operating the traffic controller accordingly while the rain intensity is above the threshold.

摘要： A vertical reflectivity composition method for weather radar display is disclosed. Rapid visual updates from incomplete NEXRAD Doppler radar volume scans advance the current state of the art for real-time tactical awareness purposes. Continuous groups of plan-position indicator (PPI) scan radials are composited onto a base array of constant per-radial azimuth defined by the initial scan of the volume. A novel variable-altitude plan-position indicator (VAPPI) method is employed to interpolate reflectivity echoes according to surface proximity within the VAPPI volume. Dynamic adjustments to the VAPPI vertical extremum adopt the maximum detected height of an adaptable reflectivity isosurface. Linear azimuthal resampling endeavors to correct angular disjunction between new composited radials and the composite base array. Legacy resolution one-degree-width radials are bisected to maintain original high-definition resolution of the half-degree azimuthal width composite radials. Computational efficiency optimizations are employed to achieve real-time performance on inexpensive consumer hardware.
