XRAD OCEANGARD

The XRAD-OCEANGARD represents the last generation of X-Band solid-state radars, designed by ICS Technologies, for VTMS and Coastal Surveillance applications and available in different configurations according to mission requirements.

Description

The X-Band fully coherent solid-state radar family XRAD-OCEANGARD is available in different configurations according to mission requirements.

VTS APPLICATIONS

There are three entry versions, each of them exceed the level of performance Basic, Standard and Advanced set by IALA Guideline no.1111 and IALA V.128 recommendation.

COASTAL SURVEILLANCE

The fully coherent solid-state radar XRAD-OCEANGARD meets a new class of requirements by exploiting the benefits of digital waveform synthesis and processing, thus improving the coastal surveillance and unveiling any threat and illegal activities.
To pay demanding requirements, XRAD-OCEANGARD enables new capabilities by giving the possibility to upgrade its hardware and including new elaboration modules. Possible upgrades concern: transmitted power, computation capacity, additional software modules, customization of waveforms, specific radar antenna systems (fan beam, inverse cosecant squared,…).
For example, XRAD-OCEANGARD makes possible to discriminate small boats which covert behind big vessels independently from distance of the coastline.
In addition, the system can distinguish low flying objects (fixed wings or helicopters) through Doppler filtering.

Description

The XRAD-OCEANGARD is designed to exceed performance recommended by IALA Guideline No.1111 and IALA Recommendation V.128 and therefore able to detect even the smallest targets within the surrounding scenario.

The XRAD-OCEANGARD radar family is based on a fully coherent pulse compression solid-state transceiver and a radar antenna. The transceiver benefits of advanced Digital Frequency Synthesis Algorithms and employs Solid State Power Amplification in order to ensure H.24 operation with best availability.

The receiver applies Signal Processing and Digital Techniques (FFT analysis, …) for providing a clear crystal radar picture in every weather condition.To pay demanding requirements, XRAD-OCEANGARD enables new capabilities by giving the possibility to upgrade its hardware and including new elaboration modules. Possible upgrades concern: transmitted power, computation capacity, additional software modules, customization of waveforms, specific radar antenna systems (fan beam, inverse cosecant squared,…).

Key strengths

The XRAD-OCEANGARD is a high-end solid state radar with:

  • Best performance (Zero attenuation concept, Time and frequency diversity, …);
  • High-end radar array antennas;
  • Simplified installation activities and reduced footprint (Plug&Play concept);
  • Full auto-diagnosis;
  • Unbeatable reliability and reduced maintenance (no transmission belt, magnetic encoder, no consumables, …);
  • Designed as lower replaceable unit in order to make repair easy and quick
FEATURES DESCRIPTION
ZERO ATTENUATION CONCEPT XRAD-OCEANGARD radar embeds a solid state transceiver in the scanner unit, and directly coupled to the antenna. This is the meaning of ICS Technologies “Zero attenuation concept”, which provides the following technical and economic advantages:

  • Zero attenuation between transceiver and antenna unit (no waveguide path) and best radar echoes.
  • Zero maintenance on running waveguides and reduced installation costs.
  • Improved visibility in the short range (reduced main bang at minimum).
 PLUG & PLAY CONCEPT

System is provided with mil-std connectors and any connection cable is pre-assembled and tested at factory. Best quality material is used, and system is designed for a lifetime of over 20 years.

  • No more waveguides to install between antenna and transceivers
  • No cables to assembly at site
  • No more errors or necessity of special tools during installation
  • XRAD-OCEANGARD installation is simply, time saving and convenient
 EASY MAINTENANCE CONCEPT
  • The radar motor is geared with direct drive transmission. Transmission belt, which must be maintained periodically has been removed. Easy: no belt, no maintenance!
  • The radar motor is installed inside the rotation unit, not exposed to atmospheric environment, thus increasing its reliability drastically.
  • The motor gearbox is equipped with a hydraulic hose in order to make the maintenance operations (purge and refill the oil) easier.
  • The system is equipped with hollow-shaft magnetic encoder, available with single or dual encoder head. This type of encoder has the highest reliability since does not have any wearing between moving parts and does not require any maintenance other than providing a superior precision due to the absence of backlash (that is typical of encoder with chain).
  • System is designed for high availability (>99.95%).
