Defence Forces want persistent, comprehensive situational awareness without compromising their own survivability.

Current RF surveillance sensors are a choice between either being effective but vulnerable (using active sensing), or having limited effectiveness but survivable (using traditional passive sensors that only sense emitting objects). By using our passive radar (that uses pre-existing and non-sensor sources of RF energy), our clients would not only maintain their situational awareness, but will do so without advertising their presence. The ability to be aware of both active and silent objects using a sensor that is itself silent is therefore a disruptive capability for Defence.
