The transceiver tract influence on the characteristics of positioning systems with a chaotic probing signals

摘要

In this paper the investigation on the special aspects of usage of broadband chaotic signals in the systems of precise positioning and radiolocation is done. The results of the numerical experiment on the investigation of the influence of the productivity of the analog-digital converter (ADC) and additive white noise in the radio channel on the performance and working efficiency of the system are presented. As the probing signal the real chaotic microwave broadband signal is used, generated as the result of the experimentation with a microwave generator of chaotic oscillations based on IMPATT diode. The results of comparison of resistance to destabilizing factors of the two main methods of processing of chaotic probing signals are discussed. These are the correlation method and the method of double spectral processing.
