Abstract

The invention relates to a method for designing a satellite-borne SAR echo data frame header identifier detection function module in the technical field of satellite-borne SAR echo data frame header detection. The method comprises the following steps: selecting the Matlab software and language to serve as a development environment of the function module design, and selecting a function form to serve as the model of the function module design; according to the function form and the external interface content, defining a function name and input and output parameters; obtaining a starting position and a data length corresponding to each pulse according to a known frame header identifier and an efficient detection algorithm developed based on the Matlab language, and implementing program development by calling related commands of the Matlab software; and performing standardized, generalized, scalable and callable package by using the packaging technology according to a developed function Mfile. By adoption of the method provided by the invention, the standardized development requirements of a satellite-borne SAR ground mounted satellite integrated test system or a ground application processing system are met, and the efficiency of the integrated test and the ground application processing is improved.

Description

technical field [0001] The present invention relates to the technical field of spaceborne SAR echo data frame header detection, in particular to a design method for a spaceborne SAR echo data frame header identifier detection function module. Background technique [0002] The satellite-borne SAR echo data is transmitted to the ground through the digital transmission subsystem, and the ground data transmission server decodes the echo data transmitted by the satellite to generate multiple transmission channel data. In order to facilitate data management, it is usually necessary to The channel data is regularly combined to form a .dat combined data file. In the subsequent data processing process, it is necessary to first detect the frame header identifier of the combined data, so as to perform data format conversion and subsequent data processing according to the frame header position information and frame length information obtained from the frame header identifier detection r...
