A Mobile 4D Imaging Radar System Network for Home Land Security

Abstract

This paper presents an innovative applicable work on modeling and implementation of mobile networked 4D Imaging Radar System as an optimal solution aimed to maximize the security of land and maritime borders. While detection limits and recognition capabilities have progressed in modern border surveillance systems, those systems still suffer from the inability to firmly identify potential threats that can penetrate land or maritime borders. The proposed radar system can significantly outperform classical radars jointed to cameras because of its ability to positively identify distant targets, sending clear real-time images across microwave channels or fiber-optic lines to command and control centers. The paper presents the functional block diagram of the 4D imaging radar, formulating its radar range accuracy, speed, and azimuth accuracy equations for moving targets. An adaptive signal processing technique for received radar signals is proposed to construct realtime video that accurately identifies moving targets regardless of adverse weather conditions over greater ranges that typically degrade the performance of current optical and thermal cameras.
