Execution Time Estimation of Signal Processing for Passive Radar

摘要

Passive radar detects a target using the existing radio wave. One of the problems of passive radar is that it takes long execution time to detect reflected waves from targets. For practical use, it is necessary to estimate this execution time. In this paper, we propose the estimation method of the execution time and show the estimation result of example case. The proposed method is partially utilizing an execution time based on small size problem. Also this method uses the number of complex number operations. The error of the estimation is 20% or less to total execution time.
