Problems solved by technology
[0004] However, the radar signal processing often "pulls one hair and moves the whole body". When the parameters need to be adjusted for a special area signal, it often affects the signals in other areas. However, the target environment in the radar coverage waters is complex, especially inland waterways. , with dense targets, many obstacles, and serious interference, it is difficult to find a set of reasonable parameters to meet the observation needs of all areas

The invention discloses a method for processing radar signals in sub-regions. Firstly, the collected radar raw data is standardized, and global signal processing parameters are set; then, the quality of radar signal processing in a specific region is analyzed to determine whether special processing is required; If special processing is required, draw a special processing area, and set corresponding signal processing parameters for the current area. After running for a period of time, evaluate and correct the parameters set in the special processing area, and finally obtain several sets that can apply to a radar power coverage area. Signal processing parameters in different regions. The present invention achieves regional processing of radar signals through methods such as area division, personalized setting, parameter evaluation and feedback, so that the quality of radar signals within the radar coverage reaches a relatively good state, and can be adapted to inland waterways, seaports, The environment of water areas such as anchorages is complex, and the interference of signals such as occlusion and secondary reflection is reduced, thereby improving the signal-to-noise ratio of radar signals.
Description
technical field [0001] The invention relates to the field of radar signal processing, in particular to a method for subregional radar signal processing, which can be applied to various industries such as ship traffic management, navigation management, shipping logistics, ship dispatching, and fishery resource area management. Background technique [0002] The application fields of radar signal processing technology are very extensive, involving meteorology, missile manufacturing, space satellite, aviation and so on. Since the early 1940s, people have begun to use radar for target, meteorological, and marine environment observations. After years of development, radar has become an important part of many civilian fields. On the modern battlefield, radar has become an important part of various military weapons and equipment. According to different radar application technologies, radar can be divided into pulse Doppler radar, phased array radar and synthetic aperture radar. Vari...
