Abstract

The invention provides a method and device for controlling time sequence synchronization of a radar system. The method includes: initializing the radar system, and mechanically scanning; outputting afirst window signal in mechanical scanning; detecting a rising edge in the first window signal, and outwardly transmitting M pulse period signals and receiving M pulse period signals through an antenna; subjecting the received signals to down-conversion processing to form samples; generating a second window signal according to the signals; according to the second window signal, subjecting the samples to data sampling and storage; stopping data sampling after mechanical scanning is finished. Time sequence synchronization in nonuniform and staggered pulse repetition period signal transmitting and receiving and sampling is realized. High-precision synchronous signals are provided for radar, time sequence control of the radar system is realized, the echo signal-to-noise ratio is increased, andaccordingly detectivity is improved.

Description

technical field [0001] The invention relates to the field of radar technology, in particular to a method and a device for controlling the timing synchronization of a radar system. Background technique [0002] Cloud and rain measurement radar uses the scattering effect of cloud, rain and other scatterer targets on electromagnetic waves to detect the concentration, distribution, location and intensity of precipitation in the atmosphere or water droplets in the cloud; it can also use the Doppler principle to obtain the effective illumination of cloud and rain measurement radar signals. The estimated value of the average radial motion velocity and velocity spectrum width of precipitation particles in the volume can further invert the atmospheric wind field, the distribution of vertical airflow and turbulence conditions, etc. Severe weather warning has broad application prospects in agriculture, transportation, atmospheric physics research and other fields. [0003] The cloud a...
