A Fire Control Radar Echoes Based On Hla Federate Development

The technology of radar system simulation plays an important role in the process of design of radar system. High Level Architecture (HLA) is the standard protocol of the distributed interactive simulation, and it has the features such as interoperability, reusability and extensibility to the simulation resources. Using HLA on the technology of radar system simulation, it has a very important significance for quickly build a radar simulation system and the performance analysis and evaluation of radar.The main content of this dissertation is as follows:1.This dissertation researches the technology of ground-based fire control radar echo simulation and the distributed simulation based on HLA, accomplishes the federate of the echo generation in the distributed simulation system and describes detailedly the implemental details. The main content of this dissertation is as follows:2.This dissertation researches the method of modulation of radar transmit signals, analyzes the transmit signals which has large product of time width and band width and why it could improve the rang resolution. Meanwhile, this dissertation structured the calculated expression of moving target echo signals based on the"stop-jump"model.3.This dissertation analyzes the simulation method of noise and clutter, researches the model of amplitude and power spectrum of ground clutter, proposed the method of coherent clutter simulation and accomplished it detailedly.4.This dissertation introduced the software named FEKO which can be used for various types of electromagnetic field analyses involving objects of arbitrary shapes. Summarizes some experience and skills in the calculation process, finally, gives calculation examples of two common targets.5.This dissertation Introduced the distributed simulation based on HLA, and we design and accomplished the federate of echo generation use Object-Oriented technology in the compiler of vs2005. Add the federate into the simulation federation to verify the accuracy of the federate, gives the result of the system simulation.
