Reverse Modeling And Simulation Of Radar Radiation Source Based On Data

In the electronic reconnaissance, intelligence based modeling and simulation of radar target. As the intelligence of true and false with some degree of instability. So in general the modeling and simulation,simulation modeling of parameters often affected the credibility.With the domestic and foreign electronic reconnaissance situation needs,the development of computer technology and maturity of the modeling and simulation of radar system. According to the time domain, the radar electronic reconnaissance obtained in the frequency and space domain information, to discuss and study how to through the above information, inversion of radar target modeling and simulation parameters and radar working system and model, reverse modeling and simulation of radar target. In order to achieve the purpose of speculation of enemy strategic tactical intention. In this paper, the specific work is as follows:1. Discussed the necessity of reverse modeling and simulation scheme of radar radiation source and meaning of data based on. Combined with the development of electronic reconnaissance mainly at home and abroad and the computer simulation technology, demonstrates the importance of the scheme.2. According to the radar emitter signal intercepted radar reconnaissance system after reconnaissance signal processing time domain, frequency domain radar, spatial information, sent to the radar inversion model, deduces the radar antenna, transmitting, receiving component information, and transmitting waveform parameters, signal processing parameters and model, and then the same data input in the form of radiation source the recognition module evidence for radiation type, type and use of recognition. Comprehensive two aspects of information, stored in a parameter management module of radiation source. These information provide radar pre modeling module, obtains the primary radar model, the correctness of the model needs to be validated, verified by the standard model of radar in the simulation or experimental conditions were obtained. The simulation data, simulation results will be fed back to the source of radiation parameter database are compared, and the calibration data obtained from simulation, radar model more perfect.3. Introduction of radar radiation source recognition module, specific design andimplementation of the inference module. Through the C-F model rules of knowledge representation, the radiation source recognition expert on radiation source recognition knowledge rules, will be given by the electronic reconnaissance data, and then as the input modules, according to conflict with the reasoning method of a series of ruling way, in accordance with the human expert reasoning logic radiation source type.4. According to the low PRF instance identification to the pulse Doppler radar, the simulation of the signal processing part, and gives the simulation image signal processing part and make specific description.5. According to the scheme may improve the place of prospect, is proposed based on the amount of data and data reliability can be guaranteed, the recognition method based on neural network. And the prospect for the radiation source recognition from types to identify models.
