| The simulative test system of middle-baseline interferometer is a new generation of test system with multi-purpose high accuracy, which using by the technology of digitations and the software. The system can complete to test range error with the missile-mounted transponder, simulate ground-based radar system of the middle-baseline interferometer .The signal-processing extension is a core part of the simulative test system of the middle-baseline interferometer and it realizes whole system's control and signal processing.The article is theoretically introduced technological design process of signal processing extension, the options of its proposals and it also provided the designs for signal processing extension in terms of hardware and software. The main content is as follow:The article theoretically provides general proposal about signal processing extension and its working principles and it indicates that major functions and technological index about signal processing extension according to different circumstances. In terms of design of hardware, the article shows that the options of hardware, the principles of design, the requirements and the theoretical proofs of major parameters, which is influence by major index. In terms of software, the article shows that the thoughts of its design, the constitutes of its software, the basic principles and design of different functional module. Finally, the detail measurements about signal processing extension in terms of reliability, maintenance and usefulness will be given. |
