Passive Radar Identification SysteM (PRISM)

BAE Systems' Passive Radar Identification SysteM (PRISM) family of Electronic Support Measures (ESM) comprises a series of modern, affordable equipments for shipborne and land applications.

The open, VME based, systems architecture of the PRISM III ESM system supports a scalable Electronic Warfare (EW) capability which can be readily tailored to satisfy specific customer requirements.

PRISM automatically detects, direction finds and classifies emitters operating in the microwave frequency band, giving extended situational awareness and immediate warning of potential threat emitters.

The latest version is installed on the Royal Australian Navy's Huon Class Minehunter Coastal vessels as an integrated part of the Anti-Ship Missile Defence System.
