Abstract
The worked out methods of improvement of a resolution of a matching filtration in time domain of the short broadband signals with the use of linear modulation of frequency (the so-called chirp signals) which product BT does not exceed 100 and initial frequency is between 0 and B are studied in this work. Influence of a smoothing window and non linear operations as well as an initial phase and a sampling rate of the short chirp signals on their compression have been investigated in order to significant increase a ratio of a main lobe to side lobes of convolutions. The best result of the compression occurs when at the same time there is used a rectangular window, the non linear operations on the convolutions and the found out optimal parameters of the short chirp signal.
