Minimizing of influence of synchronization lack between short LMF signal and filter on its compression

As researches show, the compression in the time domain of short single chirp (LMF) signals with low BT depends significantly on both matching the signal and matched filter (MF) impulse response (IR) parameters to a specific window and using non-linear operations on convolutions. These ways are effective only when a synchronization between those signal and MF is obtained. This work depicts as the above mentioned methods as a way of minimizing of influence of the synchronization lack. The proposed matched filtering method with the use of n parallel MFs and the other techniques allows only one sample to be obtained in the main lobe with position located in the appropriate sampling period Ts with accuracy Ts/n. These approaches are expedient for use in radar and sonar array processing.
