The Passive Broadcast Detection System (PYAS) Project aims to use a distributed and synchronized structure consisting of 4 sensors in order to detect signals broadcast from target platforms, generate 3D location data, track and diagnose. Since the project does not broadcast in the environment, it has the ability to perform precise target positioning without being noticed and can work effectively at long ranges. It can also perform ELINT (Electronic Intelligence) missions thanks to its ability to perform detailed signal analysis. The main features of the project are as follows: 1) Passive detection in wide frequency band, 2) Sensitive time synchronization (GPS and PTP), 3) 3D positioning with Time Difference of Arrival (TDOA) method, 3) Target tracking, 4) Impact radar, SIF/IFF transponder, TACAN/DME interrogator, jammer and Link16 signal detection, 5) Making detailed signal parameters (PA, PW, PF, PRI, Scan Type etc.) estimation, 6) Remote or local control, 7) Ability to produce output in AWCIES/ASTERIX formats.
The PIAS Project is an important step towards the development and use of high-sensitivity passive sensing systems. The project provides important information by detecting broadcasts of target platforms, generating location information and analyzing signals.
