Annotations languages:

The article, based on mathematical modeling analyzes changes in the spectrum of amplitude fluctuations of the reflected signal from the target group. As the probing signals are used to changing from pulse to pulse frequency. The main attention in the article the consideration of the dependence of the modulation harmonics occurring in the reflected signal, the number of objects belonging to location the group purpose.
Keywords: spectrum of amplitude fluctuations, harmonic modulation, the group purpose
