RÉSUMÉ

The estimation of synchronization instability becomes relevant in subsurface radar due to the fact that this phenomenon affects the accuracy of recording and reproducing the received signal forms and, accordingly, upon the efficiency of use of various digital signal processing algorithms. The existing method for estimation of jitter of the subsurface radar receiver using errors of the converted signal amplitude is not universal and should be corrected for the case of converter with incomplete charging of the storage capacitor. Simulation of the stroboscopic conversion with instability of sampling interval for cases of full charging (when the evaluation method gives correct results) and incomplete charging of the storage capacitor has been done in this paper. The relationship between the forms of probabilistic distribution of jitter and errors of amplitude after stroboscopic conversion has been analyzed. The jitter values originally specified in the simulation and the ones calculated (reconstructed) by a known method have also been analyzed. According to the simulation results, the limits of applicability of this method were determined. It is shown that the direct application of the jitter evaluation method which is true for the converter with a full charging gives incorrect estimates for the one with incomplete charging of storage capacitor. Due to this, the signal amplitude recovery procedure which allows obtaining a correct estimate of the jitter of synchronization of subsurface radar receivers operating in the mode of incomplete charge storage capacitor has been suggested.
