Problems solved by technology

There are two disadvantages of using this method: on the one hand, since the formula contains operations such as logarithm, square root, multiplication, and division, it takes more resources to use hardware or software to perform these operations in practical applications, and the calculation on the other hand, it is difficult to describe the distribution of sea clutter in actual situations by using a limited sea clutter model

Abstract

The invention discloses a sea cluster parameter obtaining method for a ship radar, which obtains a sea cluster parameter by performing processing of sampling quantization, drawing or insertion, fast accumulative total, average value removing, accumulation and averaging on an echo signal for the ship radar. The sea cluster parameter obtaining method is applied to suppression of the sea cluster in processing of the ship radar signal, can simply and fast obtain the sea cluster parameter, and avoids the shortcomings that a traditional obtaining method for the sea cluster parameter has complicatedcomputing and can not reflect sea cluster distribution in a practical sea area in real time in the practical application.

Description

technical field [0001] The invention relates to a method for processing marine radar signals, in particular to a method for acquiring sea clutter parameters of marine radar. Background technique [0002] Marine radar is widely used in fishing boats, cruise ships, warships and other ships, and plays an important role in ship navigation, obstacle detection, and target tracking. Marine radar signal processing technology is a key factor affecting the display effect of marine radar images, and sea clutter suppression is an important link in marine radar signal processing. It plays an important role in effectively filtering out sea clutter and clearly restoring marine radar images. important influence. [0003] At present, most of the sea clutter parameters of marine radar are obtained by establishing sea clutter models based on the marine environment where the ship is currently sailing, and calculating them through complex sea clutter parameter calculation formulas. There are t...
