Abstract. The problem of improving detection probability for PIR detectors is reviewed. A method based on creation of several directional diagrams optimized for various intruder models is described. Multi-element pyroelectric sensors and corresponding multi-channel signal processing are proposed.
Keywords: passive infrared detector; multi-channel PIR detector, directional diagram
