###### Abstract  
This paper is devoted to the application of object localization and identification with information combined from a radar system and a dedicated portable/mobile electronic device equipped with a global positioning system (GPS) receiver. This device is able to provide object's (staff member, and staff vehicle) rough location and identification. Such systems are required in very restrictive security areas like airports (e.g., open-air area and apron). Currently, the outdoor area of the airport is typically protected by a surveillance system operated by security guards. Surveillance systems are composed of different sensors, video and infrared cameras, and microwave radars. The sheer number of events generated via the system can lead to fatigue among staff, potentially resulting in the omission of critical events. To address this issue, we propose an electronic system equipped with a wireless module and a GPS module. This approach enables automatic identification of objects through the fusion of data from two independent systems (GPS and radar). The radar system is capable of precisely localizing and tracking objects, while the described system is able to identify registered objects. This paper contains a description of the subsystems of a portable/mobile electronic device. The fusion of information from the proposed system (rough location and identification) with the precise location obtained from short-range radar is intended to reduce the number of false alerts in the surveillance system. personal localization and identification; airport prone security; GPS positioning; data fusion; surveillance radar +

A sudden intrusion must result in a rapid and appropriate guard response. Let us focus on the airport's outdoor security systems, which can be divided into two groups:  
* Internal security: within the terminal area and passenger and baggage services;
* Outer area security: traffic handling and aircraft runaways (prone), airport infrastructure (fuel tanks and hangars), and perimeter fencing. The events of 11 September 2001, highlight the contrast between the technical protection inside the terminals and the complete lack of electronic security in the open area of the port--_no perimeter protection_. Perimeter protection is an element of physical security that arises from the possibility of individuals or groups infiltrating critical airport infrastructure. Its importance increases with the terrorist threat to the country concerned. It is assumed that the warranty for such perimeter protection should be 12 years, and the design should take into account advances in the techniques of breaching systems. An airport should be fenced with a minimum height of 2.44 m, signs should be placed every 30 m, a patrol road should be placed on the inside of the fence, and technical underground channels should be built around the fence to allow for installations: lighting, CCTV, and, e.g., motion detection systems. Such a passive system mainly protects against animal intrusion and requires constant monitoring (event validation). Other examples of perimeter protection elements are the following:  
* Ground (surface) sensors: microwave barriers, infrared sensors, lasers, and radars;
* Fence-mounted sensors: microphones, vibration detectors, piezoelectric sensors, and fiber optics;
* Buried sensors: seismic, hydraulic, and magnetic sensors. The most common fence protection is fiber optic. This allows for continuous signal analysis, precise selection of alarm events, and a wide range of tuning to the environment (e.g., depending on wind strength).
