Abstract

The invention relates to a Doppler radar and an installation method thereof, which belong to the technical field of speed measurement radars, and solve the problems that the appearance of an existing Doppler radar is not conformal with a carrier, the needed installation space is large, the installation precision is low, and the performance of the radar and the overall performance of the carrier are seriously affected. A Doppler radar comprises a radar main body and a main body frame, and the radar main body comprises an antenna extension set, a transmit-receive assembly, a receiving extension set, a signal processing extension set, a wiring extension set, a power supply extension set and a filter. The main body frame is provided with an internal cavity, and the extension sets are arranged in the internal cavity of the main body frame in an extension set stacking mode. The Doppler radar has the advantages of miniaturization, light weight, high speed measurement precision and convenience in installation and maintenance.

Description

technical field [0001] The invention relates to the technical field of speed measuring radar, in particular to a Doppler radar and an installation method thereof. Background technique [0002] Doppler radar, also known as pulse Doppler radar, is a radar that uses the Doppler effect to detect the position and relative velocity of moving targets. Doppler radar contains range gate circuit, single sideband filter, main beam clutter suppression circuit and detection filter bank, which can better suppress ground and object interference. Doppler radar can be used for airborne early warning, airborne interception, airborne navigation, low-altitude defense, fire control, battlefield reconnaissance, range measurement, satellite tracking and weather detection, etc. [0003] There are many kinds of existing aircraft, including airplanes, unmanned aerial vehicles, aerospace equipment, and electronic equipment. Doppler radar is used to provide navigation information such as three-axis s...
