Abstract

The invention relates to a full-solid millimeter wave cloud radar calibration probe system and method. The full-solid millimeter wave cloud radar calibration probe system comprises a control module generating control signals, a signal generation module, a millimeter wave receiving module, a full-solid emitter, an antenna feeder sub-system, a signal processing sub-system and a master control module, wherein the signal generation module generates one test signal and two emitting excitation signals according to the control signals within the same period in a set time sequence, the millimeter wave receiving module carries out amplification and down-conversion processing on received test signals and target probe echo signals, the full-solid emitter generates probe signals according to the two emitting excitation signals, the antenna feeder sub-system is used for radiating the probe signals to the space and the target probe echo signals, the signal processing sub-system is used for processing the test signals and the target probe echo signals, and the maser control module is used for displaying and recording a received signal processing result. The full-solid millimeter wave cloud radar calibration probe system generates the test signals and emitting probe excitation signals within the same period and realizes real-time on-line calibration of a receiver. Two emitting excitation pulses work alternatively, the power of radar probe is improved, and meanwhile low-altitude blind area coverage is realized.

Description

Technical field [0001] The invention relates to the technical field of radars, in particular to an all-solid-state millimeter wave cloud radar calibration detection system and method. Background technique [0002] The all-solid-state millimeter wave cloud radar is mainly used for the detection of targets such as clouds, fog, and weak precipitation. It uses the scattering effect of small particles on electromagnetic waves to continuously measure the echo signals of the air-like targets on the site and obtain high-temporal-resolution meteorological target information , With omni-directional, all-weather observation capabilities, widely used in atmospheric science research, artificial weather modification, cloud automatic observation, airport weather support, military weather support and other aspects and fields. [0003] The original all-solid-state millimeter-wave cloud-measuring radar adopts a single working waveform design in the same working cycle, so system online calibration an...
