The article presents a mathematical model of signal formation in a single-cable detection system based on a leaky-wave ported coax provided that the distributed receiving antenna is situated far from a transmitter.

The article reveals the mathematical model of intrusion detection system signal formation development. The case of mono-line leakywave ported coax sensor is studied. Distributed receiving antenna is studied within condition of remote transmitter. Signal formation abstract model of the issue according to the previously presented procedure is suggested. Within imposed restrictions and basing on radio-waves over flat Earth propagation classical equations, receiving cable model and bistatic scattering the mathematical model is developed. For intruder adequate description The Miranda human radar model is used. Comparison of experimentally measured signal to numerical simulation result verifying the model adequacy is also represented.
