Design And Realization Of The Radar Signal Sorting And Tracking System

With the development of electronic technology and the increasing complexity of the radar signal environment, the radar signal sorting and tracking become more and more complicated.The radar signal sorting and tracking is a key component in the signal processing.Therefore, new ways should be considered to improve the performance of the radar signal sorting and tracking.In this paper,the signal sorting and tracking is researched under conditions of complex signal envirnoment high density.Firstly the present stage of the signal sorting and tracking at the home and abroad and the increasingly complex signal envrionment are analyzed.Secondly,on this basis several commonly used sorting algorithm and their performance comparison are introduced.At last,the Combination of the SDIF algorithm and sequence search algorithm is proposed in this paper.Two-way DLVA signals which are from Microwave front-end are video signals.Pulse envelope may be leaded to a serious distortion bescause of the multi-path effects.If the distortion of the signal pulse parameters were measured directly,it will make a large error and bring problems to the signal sorting.Therefore,in the measurement of the parameters,the signal from detector should be processed. A new stream of analog signal processing method is proposed in this paper. The signal flow in the amount of the DC bias can be removed and the noise can be reduced at the same time.The effect of new methods of signal processing flow of follow-up has played a very crucial role.The new sorting tracking program is accomplished by using DSP and FPGA as the main chips in the hardware platform at the end of the paper.The details of the hardware circuit structure design and software design are introduced in the paper.The results of the sorting and tracking system also needs to be reported to the computer,therefore,the paper has completed the communication between the computer and the sorting and tracking system.The boot mode,independent mode and database mode are setted according to the instruction of the computer. So that the control of this system is more simple.After large quantity tests,the validity of the overall system is proved.It has been proved that the sorting and tracking system has strong sorting and tracking ability for complex signal environments.
