| With the development of Radar technology,Radar system has been more diversiform and complicated,which make ECM face much more complex electromagnetic environment. How to sort and analyze signal exactly is an important research of ECM. In this paper,we mainly research the signal sorting,system simulating and DSP realizing:1.The paper introduces the environment of ECM and analyses the character of time domain,frequency domain,air space,power density and polarization detailedly. We put forward the main basis of signal sorting system for ECM.2.Carry out the digital simulator of signal source. First analyze the affect of the parameters range of signal source,the error and the parametric variation on sorting result , finally constitute a model to produce the signal data and form the PDW.3.Make a study on multi-parameter sorting method for radar signal, which uses the parameter including PRI, PW, RF and DOA. Discuss the method's flow, thought, arithmetic and simulation .Make an emphasis on improving fast PRI sorting arithmetic which can satisfy the real time requirement.4.Deeply study on sorting method using independence component analysis (ICA) algorithm for radar signal. Carry out the radar sorting and analyzing system simulation on the MATLAB. Discuss the reason about the instability of result thought geometry analysis and provide a settlement in the emluator. At last, we compare ICA to the multi-parameter method.5.Otherwise, the paper is concerned with/introduces the property and application of the new float DSP chip TMS320C6701, the structure of TMS320C6701 EVM board and the software Code Composer Studio (CCS). The algorithms mentioned above are testified on the board. |
