SAAB recibe orden por radares Giraffe 4A

Saab receives Swedish order for Giraffe 4A and Arthur rada

Army Recognition


Saab has received an order from the Swedish Defence Materiel Administration (FMV) to develop and maintain the armed forces’ artillery and weapon locating capability. The order includes Saab’s Giraffe 4A multi-function radar and life extension of the artillery locating system Arthur.

Deliveries of the modern ground-based multi-function system Giraffe 4A and the life extension of Arthur will create conditions for the Armed Forces’ long-range surveillance capability in the long term and give the defence new possibilities to handle existing and future threats. The work will take place at Saab in Gothenburg with deliveries from 2019.

“Our ground-based radar Giraffe 4A strengthens our customers’ capability to detect incoming threats including tactical ballistic missiles. Tensions around us are increasing and the system gives our customers a world-class multi-function capability that helps to protect their interests”, says Anders Carp, Head of Saab’s business area Surveillance.

Giraffe 4A is a multi-function radar that gives the user a range of capabilities, one system can be used for air surveillance and air defence as well as warning and artillery locating tasks. It is a digital multi-channel system featuring Active Electronically Scanned Array (AESA) technology based on gallium nitride (GaN).

Arthur and the Giraffe radar family are produced at Saab’s Gothenburg premises, a world-leading centre for microwave and sensor technology. Several of the most advanced radar and sensor systems available on the market are produced there. Saab’s radar and electronic warfare offer also includes the airborne surveillance solution GlobalEye, sensor systems for the Gripen fighter and the self-protection system family Arexis.

Marines Test Hughes Radar 


Dispen Kormar (Hambalang). Marine Corps Navy conducts Radar / surface type Radar observation and coaching, Radar Hughes or known Ground Surveyland Radar System (GSRS) at Bukal Hambalang, Sentul Bogor, West Java, Wednesday (15/02/18).




This function test is performed to determine the ability to detect, know and identify enemies that move in the form of vehicles and personnel continuously from 360 degrees and can be made Zone Clearing Alarm that can detect enemies entering certain areas. which is planned to strengthen the Marine Corps Alkapsus become more modern, especially the Marine Infantry Battalion and Marine Corps Artillery.




Radar Hughes provides a complete radar-based mobile surveillance solution for vehicle integration, The system can be deployed as a single SharpEye SxV mobile radar integrated with telescopic vehicle pole systems or self-contained trailers.




With SharpEye radar as the main detection sensor, security regulators and patrols can monitor and intercept threats in remote places and find it difficult to access locations in a long span. The cellular surveillance radar solution enables frequent and easy location movement with immediate deployment and control capabilities within seconds of radar and camera upgrades.

Australia se hace un potente radar de penetración terrestre para combatir IEDs

ADF Combating IEDs with Ground Penetrating Radars


Husky ground penetrating radar detection vehicle

Vehicle-mounted ground-penetrating radar (GPR) equipment has been used by the ADF to detect Improvised Explosive Devices (IED) for several years, but there remains much room for improvement in the signal processing component of the technology.

A recent trial between the US and Australia provided the opportunity to test the performance of vehicle-mounted GPR equipment on different soil types, says Defence researcher Canicious Abeynayake.

“Defence’s areas of operation change from time to time, so we need to have algorithms that are robust enough to work well with different soil types,” Abeynayake explains.

“Countries using the GPRs have recognised the need to optimise and enhance automatic target recognition algorithms to match local conditions and that’s why we wanted to test the equipment in different geographical locations.”

The eventual aim is to have a fused approach to IED detection – combining the strengths of mature IED detection technologies such as cable detection, metal detection and radar.

“If we can combine all three we can improve detection probability and reduce false alarms. That’s our aim,” says Abeynayake.

Trials pave the way for improvement

The major challenges in IED detection using GPR are caused by the localised variation in terrain and climate, and the variety of IEDs encountered. Predicting GPR performance in diverse operational scenarios requires understanding the capabilities of GPR in relation to the physical properties of soils.

Over six weeks the teams drove the US Polaris and ADF Husky GPR vehicles up and down lanes of Australian soil at sites across Australia that had been seeded with objects representing IEDs. The accumulated raw data will be used to assess improvements to the processing algorithms.

Abeynayake says the Defence Science and Technology (DST) team will be investigating the algorithms at the lowest level to see which components are underperforming in different soils and against different targets.

Signal processing important for GPR effectiveness

The quality of the signal processing algorithms plays a very important role in the ultimate effectiveness of a GPR system by transforming signals into meaningful information for the operators.

Yet Abeynayake says some current approaches to target identification in GPR lack a solid theoretical basis in the underlying physics, which is fundamental to understanding the responses from GPR.

“Only when target and clutter characteristics are both well understood can signal processing be applied effectively,” Abeynayake explains.

“As targets of interest and operational environments keep changing we need ongoing research into advanced sensor configurations and algorithms.”
