Surveillance & Recon

Receive, signal-processing and antenna-control assemblies for low-altitude radar, the next-generation short-range air-defence radar and the counter-battery radar Ⅱ, together with compact, lightweight EO/IR signal processors — circuit-card assemblies designed and produced at every level from system to board.

Low-Altitude Radar

Within the system hierarchy — array antenna and digital-conversion assembly at system level, T/R control assembly at board level — Digitron develops the digital-conversion and transmit/receive control assemblies.
