Abstract:

A weather radar with an integrated flat plate slotted array antenna system mounted to a motorized, gimbaled platform. The integrated antenna system includes a substrate integrated waveguide (SIW) receiver/transmitter antenna integrated with other printed circuit board (PCB) layers. The PCB includes radar transmitter, receiver and processing circuits configured to communicate with weather radar display and controller units. A protective shield provides radio-frequency (RF) shielding and mechanical support for the integrated antenna system.

International Classification:

G01S 13/95

Abstract:

Systems, methods, and devices for processing a radar return signal to estimate reflectivity values. An example weather radar system includes one or more antennas configured to transmit a radar signal generated by a transmitter and deliver a radar return signal to a receiver. The example weather radar system further includes one or more processors configured to sample the radar return signal, determine a first signal power measurement of the sampled radar return signal based on Doppler signal processing, determine a quality of the first signal power measurement, and estimate reflectivity values of the sampled radar return signal based on the first signal power measurement when the quality is above a threshold. The example weather radar system further includes memory configured to store the estimated reflectivity values.

Abstract:

A method for tracking weather cells from a moving platform includes receiving, from a detection and ranging system, reflectivity data sampled for a volume of space and generating a feature map based on the reflectivity data, wherein the feature map is a representation of the volume of space that indicates locations with significant weather and generating a first segmented feature map based on the feature map that identifies the location and spatial extent of individual weather cells. The method further includes translating the first segmented feature map and a second segmented feature map, generated from data collected at a different point in time and/or space, to a common frame of reference and comparing the first segmented feature map to the second segmented feature map. The method further includes creating one or more track hypotheses based on the comparison of the first segmented feature map and the second segmented feature map.

Abstract:

A convective weather graphic element generator system generates graphic elements associated with severe convective weather for presentation on a display on an aircraft. An exemplary system employs a weather radar and a processing system. The processing system determines a value associated with the detected convective weather based on the received weather radar returns detected by the weather radar, compares the value associated with the detected convective weather with a threshold, and generates a graphic element for a region of airspace when the value associated with the detected convective weather exceeds the threshold. The display is configured to concurrently present the weather reflectivity information generated by the weather radar and the graphic element associated with the convective weather, wherein portions of both the presented graphic element and the presented weather reflectivity information of the corresponding area are concurrently visible on the display.
