The Polish company PIT-RADWAR has developed a passive radar SPL, designed for the Narew short-range air defense system.
- the developer noted in an interview with Rzeczpospolita.
SPL has been created since 2012 for MD Narew and SD Wisła air defense systems. The prototype was created in 2017. In December 2023, the Ministry of Defense announced the successful completion of the qualification tests. At the MSPO exhibition in early September 2025, PIT-RADWAR signed a contract for the supply of 46 radars for the Narew air defense system. Thus, the new system went into service.
Radar combines two methods of target detection. The first is by tracking the signature of aircraft using PET (Passive Emitter Tracking) technology, which captures the radiation of communication systems in the range, the "trace" from on-board radars and request and response signals from friend-and-foe identification systems.
The second is through passive coherent location detection (PCL), that is, through radiation reflected from aerial targets by external sources called "random transmitters", which include VHF radio stations, terrestrial digital television (DVB-T) or digital radio (T-DAB) transmitters, and cellular transmitters.
- the publication says.
SPL station: In both photos, only PET antennas are mounted on the mast on the left, and PCL antennas and one PET antenna are mounted on the mast on the right.The complete set of SPL in the basic configuration consists of 4 passive radars of the same type. The 5-axis Jelcz P112.57 will be used as the production platform for them (instead of the current 4-axis Jelcz P882D.53).
