“…to the axis connecting them, and R int,s is the distance separating dA int and dA s . Consequently, the total heat flux is found by solving the double integration above and substituting into (12). For an arbitrary geometry, the incident heat flux at the sensor can be approximated, for a distance (R) between the intruder and the sensor of more than 5 meters, as [23]…”

In this paper, we introduce a method to estimate the range of an intruder and track its trajectory by utilizing the received signal strength of the heat flux for pyroelectric infrared (PIR) sensors. To this end, we first develop a mathematical model of the received heat flux signal strength and the corresponding PIR signal for a moving intruder. The algorithm uses only two PIR sensors and the geometry of the field of views (FOVs) to perform the estimation and tracking process without any knowledge of the intruder's parameters. The tracking algorithm shows remarkable performance in estimating the intruder's parameters. The intruder heat flux was accurately estimated even at large separation distances as was the intruder path angle. Finally, the intruder's location was also very accurately estimated with sub-meter error for large separation distances.

“…There are three major technical approaches when it comes to human detection: infrared (IR) [8]- [10], optical [7], and RF-based sensors [2], [11], [12]. The most widespread solution available in the market employs IR pyroelectric sensors, which offer a low cost hardware, but incur high false negatives-to the point that they become a nuisance to the users.…”

“… They can obtain better field of view (FOV) when combined with a low price Fresnel lens array. Thus, compared with traditional video systems, the use of distributed wireless pyroelectric sensor networks can provide better spatial coverage and reduce the time restrictions of system deployment [ 7 , 8 , 9 ]. …”

Analysis of the multiple factors affecting human identification ability based on pyroelectric infrared technology is a complex problem. First, we examine various sensed pyroelectric waveforms of the human body thermal infrared signal and reveal a mechanism for affecting human identification. Then, we find that the mechanism is decided by the distance, human target, pyroelectric infrared (PIR) sensor, the body type, human moving velocity, signal modulation mask, and Fresnel lens. The mapping relationship between the sensed waveform and multiple influencing factors is established, and a group of mathematical models are deduced which fuse the macro factors and micro factors. Finally, the experimental results show the macro-factors indirectly affect the recognition ability of human based on the pyroelectric technology. At the same time, the correctness and effectiveness of the mathematical models is also verified, which make it easier to obtain more pyroelectric infrared information about the human body for discriminating human targets.
