| Abstract: | The model of 2D multi-stations TDOA (time difference of arrival) location system is established according to the working principle of TDOA technique. Delay model, TDOA location model and display model is founded with VC .Net programming, and dynamic link library is created and it is connected to simulation circuit after link library was compiled. The time domain data generated by signal mode was deferred with delayer, the deferred data was sent to TDOA location through adder, time domain data was crossed correlation. The value of TDOA location was estimated, and the fuzzy location was eliminated with least distance matching of locating solution. |
