摘要： In some examples, a system includes a weather radar device configured to transmit radar signals, receive first reflected radar signals at a first time, and receive second reflected radar signals at a second time. In some examples, the system also includes processing circuitry configured to determine a first magnitude of reflectivity based on the first reflected radar signals and determine a second magnitude of reflectivity based on the second reflected radar signals. In some examples, the processing circuitry is also configured to determine a temporal variance in reflectivity magnitudes based on determining a difference in reflectivity between the first magnitude and the second magnitude. In some examples, the processing circuitry is further configured to determine a presence of ice crystals based on the first magnitude of reflectivity, the second magnitude of reflectivity, and the temporal variance in reflectivity magnitudes.

摘要： A hazardous fire detection radar system that may be mounted on a vehicle, such as aan aircraft to detect bullets, grenades and similar projectiles that may pose a danger to the vehicle. The system may observe a wide field-of-regard (FOR) and for each projectile, determine the range of closest approach to the host platform (miss distance) and an approximate direction of origin. The FMCW radar system measures range and Doppler information for targets within its FOR and resolves Doppler ambiguity by estimating angular information (azimuth and elevation) for each target projectile. The system may estimate angular information by using a monopulse antenna pattern with the radar receiver.

摘要： A weather radar with a transmission antenna array that outputs a high aspect ratio FMCW transmission beam that illuminates an area in the field of regard in elevation and may be electronically scanned in azimuth. The weather radar includes a receive array and receive electronics that may receive the reflected return radar signals and electronically form a plurality of receive beams that may be used to determine characteristics of the area in the field of regard. The receive beams may be used to determine reflectivity of weather systems and provide a coherent weather picture. The weather radar may simultaneously process the receive signals into monopulse beams that may be used for accurate navigation as well as detection and tracking of objects, such as birds, aircraft, UAVs and the like.

摘要： 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.

摘要： A portable radar system that may leverage the processing power, input and/or display functionality in mobile computing devices. Some examples of mobile computing devices may include mobile phones, tablet computers, laptop computers and similar devices. The radar system of this disclosure may include a wired or wireless interface to communicate with the mobile computing device, or similar device that includes a display. The radar system may be configured with an open set of instructions for interacting with an application executing on the mobile computing device to accept control inputs as well as output signals that the application may interpret and display, such as target detection and tracking. The radar system may consume less power than other radar systems. The radar system of this disclosure may be used for a wide variety of applications by consumers, military, law enforcement and commercial use.

摘要： A radar apparatus with a transmission antenna array that outputs a high aspect ratio frequency modulation continuous wave (FMCW) transmission beam that illuminates a large field of regard in elevation and may be both electronically and mechanically scanned in azimuth. The weather radar apparatus includes a receive array and receive electronics that may receive the reflected return radar signals and digitally form a plurality of receive beams that may be used to determine characteristics of the area in the field of regard. The receive beams may be used to determine reflectivity of weather systems and provide a coherent weather picture. The weather radar apparatus may simultaneously process the receive signals into monopulse beams that may be used for accurate navigation as well as collision avoidance.

In some examples, the radar system further includes transmitter circuitry configured to generate a radar signal based on the first sinusoidal signal. In some examples, the radar system also includes one or more antennas configured to transmit the radar signal and receive a return signal based on the radar signal. In some examples, the radar system includes second DDS circuitry, second PLL circuitry configured to generate a second sinusoidal signal based on a second DDS signal generated by the second DDS circuitry, and receiver circuitry configured to process the return signal based on the second sinusoidal signal.
