ENIGMA IV is a combined digital IF receiver, transmitter controller and signal processor which replaces virtually all analog IF receiver components found in a traditional Doppler radar.

ENIGMA IV SDP extends the well proven concept of ENIGMA digital IF receiver for Doppler radars by additional advanced processing for Magnetron, Klystron, TWT and Solid-State radars.

ENIGMA IV is based on the most modern digital processing technology and the industry standard PC – LINUX platform.

GCP, Radar Control Processor

GCP interfaces FROG-MURAN to any radar, old or new

The GCP controls and manages data acquisition…

• Antenna positioning
• Radar transceiver functions, modes
• BITE
• Environmental data
• Security
• Local radar maintenance access functions

ATC Radar Doppler Weather Extractor, GWSP

• Operational for more than 4 years at Schiphol airport (NL)
• Now under deployment at more than 36 German and Swiss Air Force sites in cooperation with CASSIDIAN (EADS).
  

The goal of the GWSP is the improvement of safety of aircraft operations by means of timely detection and reporting of hazardous weather phenomena in the airport approach area

This information is extracted from Airport Surveillance Radars (ASR) data in parallel to the standard tracking function.

In particular severe precipitation, wind shear near the terminal approach and departure zones of an air port are processed and identified.

Thunderstorms, micro bursts and gust fronts are such critical events.

The GWSP is intended to provide fast and precise weather data extraction and display of all weather target moments

• RainReflectivity
• Doppler Velocity
• WindTurbulence
  

Range: >60nm (>100km) as available from the Primary ASR receiver

It can be either implemented as modernization, retrofit or improvement of the existing or new ASR systems

ASR radars serviced are Magnetron, TWT, Klystron and SolidState.

Weather and warning data are sent to the ATC controller workplaces in ASTERIX CAT 8 format. Other high resolution formats are available.

GAMIC software suite FROG-MURAN

• Has more than 50 weather processing algorithms, including Hydrometeor classification, DPOL rainfall attenuation correction, detection, NOWCASTING and real-time warnings.
• Specific weather phenomena detection algorithms like for MICROBURST, GUST FRONT and Severe Storm are available.

The GAMIC software system concept is completely based on UNIX platforms comprising standard UNIX workstations as well as UNIX communication facilities based on UNIX standards like TCP/IP, FTP etc. The software is based on an object-oriented approach. All applications are programmed in C++.

The GAMIC Software has primarily three parts, FROG MAS and MURAN and FROG VIS. ALL these three modules comprises the complete GAMIC software.

The main features of GAMIC software are:

• Remote control of unmanned multiple radar sites
• Remote control of multiple user sites
• Remote maintenance of radar and computers
• Centralized data, network and user management
• Management of the radar data collection from the center
• Supervision of wide area and local area networks
• Configuration and control of product dissemination
