The Simulation and Implementation of Radar Signal Processing Based on Space Domain

Signal enhancement methods are divided into two categories: spatial domain method and frequency domain method. Spatial domain is also known as image space, which is composed of image pixels. In image space, deal with pixel value by taking length (distance) as the independent variable. This is called spatial domain processing. Frequency domain processing technology is based on Fourier transform which modifies signals. FPGA device is a kind of typical device which exchanges resources for performance. With the constant improvement of technological level, its scale is bigger and bigger. The inside large capacity RAM, high speed I/O, and special-purpose DSP processing unit have greatly increased the application ability of FPGA in the field of digital signal processing. Therefore, on the new type of FPGA, it is conditional to use the design method based on models. ROM Table is used to complete hardware design and to realize radar signal processing algorithm in spatial domain.
