9U_VPX Signal Processor

1 Introduction

1.1 Product Overview

The 9U_VPX Signal Processor is a high-speed data recording, storage, and processing system designed for front-end RF systems. Developed to address the multiple challenges faced by military electronic information systems—such as diverse target types, increasingly complex battlefield environments, and diversified mission requirements—this system serves as a high-performance data recording and storage solution. The signal processor handles the recording, storage, playback, and management of sensor big data.

The signal processor consists of multi-port fiber modules, high-speed real-time information processing modules, integrated management and configuration modules, and large-capacity data storage modules. It provides users with the following capabilities:

Real-time forwarding and processing of high-speed data;
High-speed data recording and playback services (user data formats are customizable);
Centralized data management and retrieval services;
Support for network-based cascading and scalability;

The signal processor delivers a comprehensive solution for front-end sensor big data processing in equipment systems. It supports sensor data acquisition, data conversion, video capture, real-time processing, and record-and-playback functions. As a sensor big data server, it provides cloud-based big data system solutions for integrated information processing systems.

1.2 Key Features
