Homeland Alerter 100

Description

The Homeland Alerter 100 is a passive radar sensor using illuminators of opportunity provided by FM radio broadcasts*.

* Possible extension with DAB (Digital Audio Broadcast), AVB (Analog Video Broadcast) and DVB-T (Digital Video Broadcast –Terrestrial)

Mission

Facing an ever evolving threat, mainly at low and very low altitude, the Homeland Alerter 100 has been developed to offer operational capabilities for homeland security or projection such as sensitive site (factories, airports,…) protection, high
value event surveillance (particularly in an urban environment) and coastal surveillance.

Principles

Radio Frequency (RF) energy of transmitters is scattered from targets, correlated with the direct path signal to provide time difference of arrival (ellipsoide) and doppler measurements.
Passive radar sensor utilizes civilian electromagnetic radiations in order to detect and estimate target parameters (location and speed).

Features

• Detection performances on 360°:
  • Range: class 100 km
  • Elevation: 90°
  • Ceiling: up to 20.000 ft

• 24h/7 all weather surveillance
• Configurable for mobile platforms or fixed sites:
  • Commercial or 4x4 military vehicle (using car driver licence)

• Stand alone or in network operations
• Connection to Command and Control Centers through Asterix/AWCIES protocol

• Delivered with a software (Aneth) for deployment support and performance prediction

Main benefits

• Detection of low speed, low altitude and stealth flying targets
• High mobility, rapid and flexible deployment
• Totally discrete
• Easy to operate
• Installation allowed in areas where active radars cannot be deployed (explosive areas, …)
• High availability and low life cycle cost due to civil technology (COTS)
• Very low maintenance and logistics
• No Electro-Magnetic Compatibility (EMC) issues
• No ecological restriction (human safety, environment protection)

In service

The Homeland Alerter 100 has already been sold to several NATO countries.
