An improved aerial target detection algorithm

摘要

This paper considers aerial target detection using an improved remote sensing method. The background is removed which can cause a lower signal to noise ratio (SNR) of the radio frequency (RF) signal. The singular value decomposition technique is used to extract the major components of RF signal. To enhance RF signal, the automatic gain control method is employed. The maximum slope and standard deviation are used to analyze the characteristic to provide two results for aerial target detection including the azimuth information and bandwidth. These estimates are used to determine if a target is present in the detection environment. The experimental results validate the effectiveness and better capability of the proposed detection method.
