FARAD

An advanced system to measure the radar cross section (RCS) of flying aircraft in operational environments

FARAD is a prototype EM measurement radar system which is designed to perform dynamic RCS measurements of high-speed low observable flying targets, including those featuring stealth technology. The system is customizable and expandable and only requires a short time to acquire accurate measurements.  It is able to measure a wide range of targets, from full size aircraft and helicopters to very small unmanned aerial vehicles (UAVs). The embedded target tracking capability is optimized for short range RCS dynamic measurement of flying targets. When being measured, the target aircraft flies planned trajectories and is automatically tracked by FARAD.

FARAD RCS of flying aircraft

The radar, tracking equipment and the cabin for its operators, and control and monitoring equipment, are all part of a rugged integrated system designed for all-weather outdoor use. They are self-powered, highly transportable and fast and easy to set up without the need of any preparation at the test site.

Main Features

RCS measurement
Measurement system for flying aircrafts
Target tracking
An embedded radar target tracking capability
High accuracy
High sensitivity and accuracy in order to measure stealth targets
FARAD Main Applications

FARAD can be utilized for a wide range of applications and by several types of user including aircraft and unmanned aerial vehicle manufacturers, air forces and Electronic Counter Measure (ECM) manufacturers:

  • For the Final Acceptance Test of a new target
  • For extraordinary maintenance during the target’s life cycle management
  • For ordinary maintenance during the target’s life cycle management
  • For the design, development and testing of ECM devices (jammers, chaff etc.) for the target’s self-protection

FARAD can be deployed along a runway at an air force airbase and operated immediately after a take-off or immediately before a landing, therefore minimizing the target’s operational flight costs (no need for a dedicated flight mission).

FARAD Main Benefits

The measurement performance is extremely flexible in terms of target radar cross section level, measurement range and target speed

Allows very fast operation and provides highly accurate real-time data

Measurement campaigns can be performed immediately after being deployed at a suitable site, minimizing service outages and time delays, and reducing the installation and operational manpower needs

FARAD - RCS Measuerement

FARAD consists of two modules which are transportable by a single van and trailer:

  1. The antenna subsystem is mounted on an equipment trailer and includes an RX/TX radar antenna assembly, target tracking equipment and positioning equipment.
  2. The van houses the control equipment and post processing computers.
