Abstract
Digital filtering is one of the most efficient technologies for processing radar signals. FIR Filters are a very important type of Digital Filters that are a vital element in radar signal processing. Synoptic diagrams called “filter realization structures” show the connections between various arithmetical operations including add, multiplications, and shifts. Finite impulse response (FIR) filters can be realized using a variety of several types of structures or realizations such as direct form, cascade form, frequency-sampling form, and lattice structure. In this paper, FIR filter structures are proposed, simulated, and implemented using the Matlab Simulink Xilinx System generator blockset. These FIR Filter structures were developed using Xilinx System Generator (ISE Win 14.7) and Matlab Simulink (Win 2013). Xilinx System Generator tool provides a good way to design efficient hardware implementation for FIR filter structures on Artix-7 FPGA kit.
