Abstract

Matched Filtering is an important part of the radar and sonar systems. Implementation of match filtering in time or frequency domain can be more advantageous due to bandwidth constraints. Another important part in match filtering is unwanted sidelobes. These sidelobes can be detected as a main part of another signal and it can be misleading. In literature, lots of methods have been proposed to reduce sidelobes. Each method has advantages and disadvantages regarding resource usage and speed. In this work, match filtering is implemented in time and frequency domain and then sidelobe reduction techniques are examined. Due to the results the sidelobe reduction methods are added to the filter implementation. Then match filter is implemented as customizable and parametric soft IP core. This IP Core makes easy to implement the match filter in any configuration.
