Saab has introduced a passive, compact electronic warfare sensor called the Sensor Compact, designed to work alone or in a group to detect incoming threats at various tactical levels without disclosing their presence.

Various defense contractors are developing sensors that are not only more sensitive to electronic input signals, but also smaller, lighter, more efficient, and able to operate unobtrusively.

Weighing only 3 kg, the new Passor Compact passive modular unit can be installed on different platforms and quickly deployed by a single soldier to create scalable detector networks where sensors can invisibly detect incoming threats in their electronic signature.

Developed by Swedish and Finnish companies, Sensor Compact silently detects, evaluates and prioritizes radar signals and data transmissions. Its standalone systems can identify potentially hostile signals or triangulate and easily obscure other ground-based transmitter targeting devices with accuracy and efficiency that Saab says is comparable to larger static sensors.

Sirius Compact can be installed on coastal and border surveillance systems, armored vehicles and small unmanned quadcopters. Areas of application include aerial surveillance, crew/robot crews and special operations. As an added security feature, Sirius Compact does not need to contain any confidential data.
