Suppression of false targets from active defense radar sensors

Military active defense systems are based on the detection of threatening missiles and their de-activation by suitable counter-measures. Often, these defense systems are based on microwave radar sensors. Practical tests indicate that when detecting threatening missiles, the process can be complicated by frequent false targets. In this work, we show that these false targets can disrupt the convergence of a Kalman filtration process for effective counter-measure actuation. More detailed analyses led to conclusions that generation of false targets is caused by two different physical phenomena. Their description and proposals how to suppress their negative influences represent the main topics of this paper.
