Realization of Electromagnetism Radiation Characteristics for Target Radar Based on SINC Function

This paper introduces how the target radar simulates radar operation,discusses how to use field programmable gate array (FPGA) look-up table method to fit the waveform of radar side-lobe by using SINC function in detail,expatiates the simulation method using parameter deploy to realize the side-lobe characteristics of different types of radars,and gives the calculation formula and realization,finally analyzes the quantitized error.The error analysis shows that the method can realistically simulate the electromagnetic radiation characteristics of radar antenna side-lobe,and also reduce the cost of development,usage and and maintenance,as well as shorten the development period.
