Paper Title
Design and Manufacturing of Automatic Object Detection and Access Control System using Doppler Radar and Xbee s1

Abstract
The purpose of this paper is to present the Automatic Object Detection and Access Control System using Doppler Radar. The inspiration for this paper is derived from Identification Friend-or-Foe (IFF) transponder systems currently used on fighter aircraft and military vehicles. Mainly, IFF system is used to avoid friendly fire attacks[1]. This paper presents generalized short range “Identification Friend-or-Foe (IFF)” prototype system to prevent friendly-attack or to detect the entry of unauthorized object in operating area. The system is low cost, efficient and consumes very low power. The same system can be used anywhere, where authentication is needed. The IFF system is designed for the short range of approximately 30 m. The object entering in radius of 30 m is detected and is interrogated to decide authenticity of detected object. If authorization is successful, then the object is classified as “Friendly Object” ,otherwise it is classified as “Foe Object”. The real time status and result can be seen on display. From this result , further necessary action can be taken Keywords - Object Detection, Doppler Radar, low cost, power efficient.
