Abstract: In the development of over-the-horizon radar, the advent of computer simulation technology promotes the development of its technology effectively. Over-the-horizon radar is often disturbed by strong sea clutter in the detection process, seriously affecting the development of the corresponding technology. As the traditional sea clutter filter considers only the suppression of sea clutter and rarely takes into account the effect of filtering algorithm on target signal in the computer simulation technology, the target echo produces great distortion after the computer simulation. This paper aims to solve the above problems by introducing the correct process of the target signal into the algorithm of the computer simulation technology. By the correction of the filter parameter, the sea clutter is suppressed and the filtering signal is corrected. In the actual simulation experiments, comparing the results with traditional computer simulation technology, we have also proved the superiority of this new filtering algorithm.
