Whether its business or pleasure, everything would be more difficult, more time consuming and less efficient.
It seeks to take away an opponent’s capability or find other ways to work around it this making the enemy’s job more difficult, more time consuming and less efficient.
Many have said that the future battlefield will be a multi-domain battlefield. But what does this actually mean? The combat zone faces new challenges that have not been conceived before. Traditional threats present themselves either in the air, on the ground or at sea. Then add space into the mix along with the trend of fighting with data and information, and suddenly, warfighters have found themselves in a congested and contested environment where receiving timely and accurate information in real-time becomes more critical.
Taking advantage of a contested and congested electromagnetic spectrum, adversaries have spent years studying the capabilities and tactics of Armed Forces to develop counter measures to dominate the electromagnetic spectrum. Measures to disrupt or deny access to and action within the electromagnetic environment from a distance were unheard of concepts when there was only one domain to be concerned with.
The future battlefield will be a multi-domain battlefield and this extends. This is known as the ‘Multi-Domain Battle’; a concept which has been developed to manage how the environment and adversaries have changed, how they will deny and disrupt and to combat this by creating a shared network across all domains of war.
To ensure survival in a multi-domain battlefield, militaries across the world are already upgrading their electronic warfare capabilities to increase their dominance in the electromagnetic spectrum. Because without spectrum dominance, the war is lost before it has even begun.
To successfully survive in the increasingly digital battlefield, effective measures are needed to identify threats to systems and to deny enemy operators the use of the spectrum.
As RF sources and electromagnetic amplifiers are developed to cover wider bands at a higher power, it is important that electronic warfare antennas needed to counteract this are developed in parallel.
What type of antenna can defeat an adversary attempt to jam or deny? One that covers all bands, with high gain for the horizon, small enough to be used by soldiers on the ground and rugged enough for heavy duty armoured vehicles. Not asking for much is it?
The portfolio of ultra wideband omni and directional antennas cover 100MHz to 18GHz frequencies where high power amplifiers currently operate.
High Power Planar Spiral Antennas are directional, ultra wideband antennas. As Chelton’s flat-panel, reflector-backed spiral has no absorber, it can handle up to 100W with an 8dBi peak gain giving an impressive level of Effective Isotropic Radiated Power (EIRP) for counter measures. Unlike omni directional antennas, planar spiral antennas provide circular polarisation which is invaluable in many scenarios particularly where the polarisation of the threat signal is unknown.
Ultra wide band omni direction antennas are efficient, vertically polarised broadband antennas and provide excellent coverage regardless of the orientation of the vehicle or man –pack it is on. Benefitting from being centre-fed and ground-plane independent, the peak gain is on the horizon across all bands so that high power can be delivered where needed.
To cover very wide bands without obvious frequency gaps, ‘Feed-Through’ technology has been developed to allow several wideband omni antennas to be ‘stacked’ so that they can be designed into a single housing unit giving a single mounting point on any platform. Not only will this overlap frequencies for multiple applications, there is also a high isolation between bands and 200W operating per band simultaneously.
We design, develop and test antennas specifically for our customers’ requirements in their goal to achieve electromagnetic dominance as they protect our territories.
