IPC: G01S3/801
Filed: 2003-05-13
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that a conventional passive sonar simulation generated from the random number of single probability density distribution cannot individually set and simulate level dispersion for each signal seen in actual data and variations in a line width, which is insufficient as simulation precision.  <P>SOLUTION: A simulation signal and background noise are generated by using a random number having probability density distribution being different for individual signal, and then are added to generate simulation data.
