Abstract

The invention discloses an integrated detection radar system and a method for an ice thickness and a water depth, which relate to the field of detection radars. The system comprises a detection radar and a terminal host provided with an ice thickness and water depth integrated detection radar application program, wherein the detection radar comprises a radar master control board and a pulse signal transceiver. The method comprises steps: parameters in need of detection and acquisition are set, and the parameters are transmitted to the radar master control board; different radar waves in two frequencies are transmitted to an ice layer and underwater in a target test area, and echo signals are received; equivalent data sampling is carried out, complete cycle signals converted to differential signals are transmitted to the terminal host, analysis processing, filtering processing and gain processing are carried out sequentially, and radar echo signal data after processing are obtained; and the ice thickness and the water depth are displayed. Fast, nondestructive and continuous detection is realized, profiles of the ice layer and the water depth structure are displayed in a real-time imaging mode, real-time voice broadcasting is provided at the same time, the detection result is clear, and the analysis and the interpretation are intuitive and convenient.

Description

technical field [0001] The invention relates to the field of detection radar, in particular to an ice thickness and water depth comprehensive detection radar system and method. Background technique [0002] Among all natural disasters, flood disasters occur most frequently and affect the largest population, which not only brings economic losses, but also affects social stability. The river basin faces the threat of two types of floods, one is storm floods and the other is ice floods. Among them, ice flood is a natural disaster with the most influencing factors and the most complicated disaster mechanism. At present, the hydrological observation of rivers and lakes in winter in China adopts the method of manual fixed-point drilling to detect ice thickness and water depth. The observation area adopts a fixed distance or determines the sampling point according to experience and then drills the hole for measurement. Only some sparse sampling point results can be obtained. , ne...
