“…Therefore, there is a serious need for innovative solutions which are more resistant to interference, with more reliable threat detection in the field of border protection. Standard existing solutions are, in most cases, based on the combination of a radar detector with video camera surveillance in the optical and thermal spectrum [3,4]. In addition, vibrational and seismic detectors and touch barriers can be added for systems that demand an even higher detection reliability [5].…”

The goal of this paper is to design a broadband acoustic camera using micro-electromechanical system (MEMS) microphones. The paper describes how an optimization of the microphone array has been carried out. Furthermore, the final goal of the described optimization is that the gain in the desired direction and the attenuation of side lobes is maximized at a frequency up to 4 kHz. Throughout the research, various shapes of microphone arrays and their directivity patterns have been considered and analyzed using newly developed algorithms implemented in Matlab. A hemisphere algorithm, genetic algorithm, and genetic square algorithm were used to find the optimal position and number of microphones placed on an acoustic camera. The proposed acoustic camera design uses a large number of microphones for high directional selectivity, while a field programmable gate array system on a chip (FPGA SoC) is selected as the processing element of the system. According to the obtained results, three different acoustic camera prototypes were developed. This paper presents simulations of their characteristics, compares the obtained measurements, and discusses the positive and negative sides of each acoustic camera prototype.

Surveillance systems are using more and more devices that use multiple spectral bands to detect threats, such as millimeter-wave radar, terahertz cameras, infrared cameras, and many others. These devices enable early detection of occurring threats. However, using such a wide spectrum of devices can significantly increase the amount of data collected by the system. This creates a need to determine the suitability of the information of individual devices, and reduce the amount of data. In this paper, the authors consider problems of data fusion from multispectral sensors and the possibilities of applications in security systems. The paper describes the opportunities and risks that potentially carry the use of data fusion, and shows the ability to detect and identify the target using data collected by multispectral sensors. A very important aspect of data fusion is to reduce the amount of data without losing contained information, and improve the readability, which facilitates its interpretation by a system operator. The paper focuses on determining the possible ranges of detection for selected multispectral devices capable of producing the correct synthesis of data.
