Applied Physics and Mathematics Annotation << Back DELIBERATE INTERFERENCES INFLUENCE ON PASSIVE DETECTION A.A. MOISEEV Here simulated passive detection of active locator disguising with jammers whose powers are lower than locator once. Directional diagram of passive detector is proposed Lambertian. In this situation estimated: • signal-to-noise merit dependence from jammers number and their characterisnics; • power characteristics of detection distance; • frequency characteristics of detection distance for spread-spectrum signal. Performed consideration allows estimating jummers influence on passive detection and also influence of power and frequency characterixtics on detection distance. Keywords: passive detection, active locator, deliberate interferences, directional diagram, signal-to-noise merit, limit distance, chords method. DOI: 10.25791/pfi m.01.2024.1286 Pp. 20-24.
