Digital Signal Processor Design for Radar Signal Processing

Today digital signal processing techniques are employed in a variety of applications. Two factors contributing to the growth in the use of digital signal processing (DSP) are the advent of custom VLSI that has made using digital signal processing techniques to solve real time problems more attractive and powerful; and the ease and flexibility of application of digital signal processing technique both in hardware and software. The purpose of this paper is to present the design of a digital signal processor chip based on a consideration of VLSI technology and signal processing requirement for radar applications. The paper reviews basic signal processing tasks , giving emphasis to the digital filters and spectral analysis which are generally the required functions in radar signal processing. That leads to the discussion of two DSP algorithms Discret Fourier Transform and Fast Fourier Transform. The basic hardware components required are described along with the software to implement the DSP algorithms. Finally, an example demonstrates the use of processor chip to perform transversal filter function
