A Synthetic Aperture Radar Inertial Navigation Data Input Method and Input Agent System

Abstract

The invention discloses an agent-based synthetic aperture radar inertial navigation data input method and an inertial navigation data input agent module. The method comprises the following steps: using an input status of inertial navigation data, an operation behavior and status of a DSP port, conflict monitoring and management at a read end and a write end of an application-level inertial navigation data cache as objects monitored and managed by an agent by adopting the agent-based technology, monitoring serial data and performing framing processing on the serial data according to an inertial navigation frame, adopting a status driving manner in the frame processing procedure, automatically monitoring the behavior of the DSP port and providing the inertial navigation data to a DSP according to a complete frame protocol on the basis of the status of the DSP port. The inertial navigation data input agent module comprises a serial port monitoring serial-parallel conversion module, a self-adaptive framing module, an agent management module and a signal processing RAM interface module. Through the adoption of the method and the agent module disclosed by the invention, the efficiency is high, the system coupling degree is low, and the operation is simpler, and the possibility of data clogging can be reduced, the differential processing is realized, the number of the clock sources is reduced, and the reliability is improved.

Description

Technical field: [0001] The invention relates to an agent-based synthetic aperture radar inertial navigation data input method and an inertial navigation data input agent system, which uses an agent-based design instead of a high-performance processor to complete receiving inertial navigation data to form an application-level frame protocol, so that the signal processor Focus on handling high-performance computing. Background technique: [0002] SAR (Synthetic Aperture Radar) is a high-resolution imaging radar that forms a virtual equivalent long antenna through the movement of the radar on the flight carrier to obtain radar images with high azimuth resolution. The synthesis of the effective long antenna by the linear motion of the aircraft is the principle of forming the synthetic aperture, which is also the problem of the synthetic aperture radar. During the flight, the motion error of the aircraft will lead to problems such as unstable beam pointing and non-uniform sampl...
