A data processing system and method

Abstract

The invention discloses a data processing system and method. A first demultiplexer divides data into data subsets of corresponding single beams, each data processor processes a data subset of corresponding single beams, and a second demultiplexer collects the data processed by the data processors and then distributes the data to a point trace acquisition module, a tracker module, a data format conversion module and a display module for processing in sequence; the system provides a low-cost solution for ocean radar to execute an advanced signal processing technology; the system is flexible in processing capability for fulfilling the purposes, and can be easily added with more SDPs (Signal Data Processors) if more processing capability is needed; and the system can bear advanced signal processing suitable for small-target detection and effective clutter suppression in real time.

Description

technical field [0001] The invention relates to the field of radar monitoring, in particular to a data processing system and method. Background technique [0002] Agencies and businesses protected by port authorities, borders and infrastructure, such as the oil and gas industry and marine transportation, require target size and detection capabilities in harsh marine environments: they require powerful signal processing techniques from marine radars. Commercially available marine radar system architectures limit the use of computationally intensive signal processing techniques, most of them rely on single or multiple threat processors with limited IQ data rates, but can only do simple signal processing techniques such as CA, CFA. Most of them cannot detect and track small boats / objects in normal sea states or normal sized targets in high sea states if clutter is increased. Although some companies have proposed to use high-end DSP processors, high-end DSPs have higher process...

Problems solved by technology

Commercially available marine radar system architectures limit the use of computationally intensive signal processing techniques, most of them rely on single or multiple threat processors with limited IQ data rates, but can only do simple signal processing techniques such as CA, CFA

Most of them cannot detect and track small boats / objects in normal sea states or normal sized targets in high sea states if clutter is increased

Although some companies have proposed to use high-end DSP processors, high-end DSPs have higher processing capabilities, which also makes these systems expensive. At the same time, relevant laws and policies in our country have also made strict export regulations.
