Skyline LogoThe Skyline radar system detects, tracks, prioritizes, and reports objects and intruders within its Field of Regard (FOR). This unique system supports land, sea and air platforms by combining leading-edge phased array antenna technology with advanced radar signal processing. Additionally, Skyline’s design utilizes FPGA technology, which provides rapid reprogramming, minimizing reconfiguration times for fast changing environments.

Description

The Skyline radar system brings together high performance, ease of programmability, low cost, and commercial I/O flexibility in a modular, open systems and standards architecture to realize an adaptable radar for multiple applications. Skyline was designed to detect, track, prioritize, and report objects and intruders within its Field of Regard (FOR). This unique system has been architected to support land, sea and air platforms by combining leading-edge phased array antenna technology with advanced radar signal processing. Additionally, Skyline’s design utilizes FPGA technology, which provides rapid reprogramming, minimizing reconfiguration times for fast changing environments. With nearly 200 hours of flight time and over $10 million invested by the USAF, Skyline takes performance and flexibility to a whole new level.

Advanced Tracking on Any Platform
Skyline’s tracking algorithms were designed using a matrix Kalman filter to support its platforms roll, pitch and yaw movements to continuously track targets.

Modular Architecture
Skyline’s digital electronics are housed in the L-shaped enclosure mounted on the back of the array with the RF modules contained in the upper left box. Both subsystem enclosures are mounted on the back of the phased array antenna. The Skyline system can be configured to support terrestrial, sea and air platforms.

Rapid Reconfiguration
Designed using cutting-edge back-end processing technology, the Skyline Radar system utilizes FPGA technology to allow for rapid reconfiguration to support multiple environments and target types.
