The method of analog location with the use of devices with SAW that is now being used in our country is fast, however it is nof accurate enough and has insufficient resistance to bofh natural and artificial noise. In the paper is proposed to increase the resistance of the digital location system by means of using a location system manipulated with noise-like code, and additional signal compression, filtration based on fast convolution and correlation analysis to isolate noise-like codes. The system proposed here easily adjusts to the changes in the code of the signal generated by the radar, and it also works in real time.
