| After Correlation identification method combined with SIP method,it would come into being Correlation-SIP method.This method can suppress the random noise greatly,at the same time,the once signal launch can get multi frequency point data received.From the sent and received data,we can get the complex resistivity spectrum of the earth in order to study the geophysical parameters.The method has strong ability of anti-noise and high exploration efficiency.The correlation identification is still in the developing and perfecting stage.This paper focuses on the correlation identification methods research and optimization methods’ design in the frequency domain,and I completed the design of electrical transmitter system based on correlation identification.And then I designed a simple circuit to verify the performance of the transmitter.The main content of this paper includes four aspects:(1)The correlation identification theory.The correlation identification theory is studied and described mainly from the perspective of frequency domain.(2)Transmitter hardware design.The content mainly introduces the front of control part,IPM part and the design of the transmitter power supply.And the core control by XC3S400 FPGA to produce and send the m sequence of functions.(3)Transmitter software design.The content mainly introduces the software part of the transmitter including control core collection with STM32F407,data storage,display and control function.(4)The actual data processing.The content mainly introduces the deal of data collected,assessment and treatment about the results.Compared with the traditional system identification,the new identification result is good.Hardware,software and theoretical research are harmonized each other.They form a whole identification system of earth system.It works properly and can be used in IP method of the earth system identification.The interface of the designed transmitter is pithy,and the operation is simple,practical and reliable. |
