| Abstract: | The physical meaning of reflection coefficients has been discussed,and the underdetermined system of equations which contain reflection coefficients has been reached in the time-domain , the method of Linear Programming for solving the underdetermined system of equations has been put forward, and the train of thought and programming frame has been given. Two theory models have been processed and the reflect coefficients have been calculated. Analysis to numeric examples shows that the algorithm is reasonable and the program is useful. This method can be used in the numerical calculation of Transient Electromagnetic Method imaging. |
| Keywords: | Transient Electromagnetic Method reflection coefficient Linear Programming |
