Full-solid millimeter wave cloud radar calibration probe system and method

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.
