Title    Design of the control and display program for Ground-based SAR imaging system 

Abstract

Synthetic Aperture Radar is one kind of high-resolution imaging radar which generates large virtual aperture antenna through the relative movement between radar and targets.In the background of target camouflage effect detection in electromagnetic environment,the control and display program of a ground-based SAR system is designed.Object-oriented programming methord is selected to design the whole program,including a login interface,a NIC initialization interface and a system control interface. One of C++ and matlab mixed programming methods is used to call the function of high-resolution algorithm.WinPcap development process is used to realize the Ethernet communication between radar system and control software.

The main functions of control and display program are as follows.

1. Motor control,parameter setting,data acquisition and storage are achieved via Ethernet.

2. Initial phase comparison,one and two-dimensional imaging are achieved via calling the matlab program of imaging algorithm.

The testing results of SAR system show that the control and display program is designed successfully.It meets the design requirement and is user-friendly.
