Embodiment 1

[0034] Embodiment 1. This embodiment discloses a method for classifying and storing massive sea clutter data. The specific steps are as follows:

[0035] (1) Build a storage system based on ORACLE RAC shared storage cluster architecture

[0036] In the construction process of the database storage system, it is necessary to analyze from the actual business requirements. If the business system is single, the historical data and incremental data are not large, and the performance and real-time requirements are not high, an independent database can be used and deployed on a PC server to meet the requirements; and for huge data volume, the core entity data model For databases that are complex, have many attributes (dozens or even hundreds), and have high requirements for real-time performance, reliability, availability, and fault recovery of the database, an advanced cluster system is required. Separation, horizontal segmentation, mixed clustering of in-memory database and disk da...

Abstract

The invention discloses a method for classify and storing massive sea clutter data, comprising the following steps: (1) constructing a storage system based on an ORACLE RAC shared storage cluster structure; (2) Constructing data storage tablespace to realize sea clutter data storage management; (3) Constructing partition mode to realize the logical classification and storage management of sea clutter data; (4) achieving combined retrieval of sea clutter data based on view virtual association technology. The type of data retrieval is determined by the actual sea clutter application scene. The sea clutter data classification storage method disclosed by the invention constructs a sea clutter data management hardware platform based on an ORACLE RAC shared memory cluster structure, so that thesystem has load balance, high availability service, expandability, and improves the transaction response time through a parallel execution technology.

Description

technical field [0001] The invention belongs to the field of storage and management of massive sea clutter data, in particular to a method for classifying and storing massive sea clutter data acquired by different radars under different sea conditions. Background technique [0002] The impact of sea clutter on the performance of radar target detection is very large, especially in the case of high-level sea conditions, different sea conditions (wind speed, wind direction, wave height, wave direction, etc.) will generate different sea surface states, different The state of the sea surface produces different electromagnetic scattering characteristics. To this end, it is necessary to collect a large number of sea clutter data of different sea state levels and different radar bands, and conduct research on sea clutter mechanism, amplitude statistical characteristics, spectral characteristics and other related aspects. Due to the rapid development of modern radar technology, the ...
