Design Of Passive Radar Seeker Software Platform Based On Rotary Interferometer

The simulation software introduced in this paper is based on the practical engineering background,and mainly simulates the whole process of the ship platform launching anti-radiation missile to intercept the target.The simulation software focuses on the passive radar guiding the anti-radiation missiles.At the same time,it simulates the functions of the ship platform to find the air target,rotate the launcher,supply the missile power,intercept the air target,display the missile and air target's track and the historical data in the datebase.The simulation software mainly use the rotation baseline interferometer algorithm to simulate the process of the seeker finding direction.The software is developed in Windows 7 system,at the same time it uses Visual Studio 2010 visual integrated development frame within the combination of RTI-DDS communication software,Oracle database,OpenGL drawing interface programming software to complete the development of multiple functions.During the process of missile's flight,the missile itself is rotated,and the missile's size is limited which requires the algorithm of the direction finding is easy to be achieved and get a good accuracy.The rotation of the baseline interferometer is based on the rotation of the two antennas.In the course of the rotation of the antennas,many short antennas with different lengths are formed,which is equivalent to the use of multiple antenna channels.It can be solved in a finite space.Rotational baseline interferometer direction finding algorithm can well perform in the direction finding of target position information during the missile's flight.The simulation software uses the dialog frame to develop the front interface to simulate the realistic operation platform interface.The simulation software uses ADO technology to link the Oracle database which can realize the data storage and display.It uses RTI-DDS communication software to realize the network data transmission;It uses OpenGL graphics interface to display missile and target flight track.In the software design stage,it isaccording to the theory of software engineering module design and demand control.First of all,we analyze the needs of the use of software company,and then begin the overall design and modular design,and finally the software black box white box test.And finally the simulation software not only can run in the local area network but also run in one computer.The software development process in this paper mainly describes the simulation of the ship platform from the discovery of the target to the final target of the process.The software uses the direction finding algorithm and guidance algorithm to draw the track which can truly simulate the missile and the target in the air flight process.This can also provide experience for future similar software development.
