An inflatable dummy target comprising a chassis of inflatable ducts wrapped with a sheet. The chassis of inflatable ducts can include one or more ring shaped ducts and one or more elongate ducts. The chassis can include at least two ring shaped ducts interconnected by one or more elongate ducts. The dummy target can include several attached axi-symmetrical sections, each section have a chassis of inflatable ducts. Each section can be conical, frustoconical or cylindrical, thereby achieving a concave or convex dummy target geometry.

A dual-mode optical and RF reflector, and test system using the same. In one example the reflector is a mirror having a reflective surface including a first zone having a first surface precision, wherein a remainder of the reflective surface outside of the first zone has a second surface precision that is substantially lower than the first surface precision, the mirror being configured to collimate and reflect an RF signal from the reflective surface, and to collimate and reflect an optical signal from the first zone.

The invention refers to a counter countermeasures device, for use in an anti-aircraft combat. In one embodiment the CCM device together with an anti-aircraft weapon system forms an air defense system. The counter countermeasures device is configured for generating and emitting electromagnetic radiation of appropriate wavelengths and is capable of operating in spoof and jam mode and switching between both modes. The mode of operation is dependent on the selection of the output power of the EM source unit and the distance to the target. The selection of the output power may be done with a mechanical cover or with an electronic solution, decreasing driving current of the EM sources. With the CCM device the anti-aircraft missile launch warning and detection system installed on aircrafts are deceived and the countermeasures are released. With the use of the CCM device the efficiency of the anti-aircraft combat is highly improved, i.e. the probability of the target hit is highly improved.

The invention refers to an air defense system comprising at least one counter countermeasures device, and at least one anti-aircraft weapon system and to an anti-aircraft combat method comprising said air defense system. The counter countermeasures device is configured for generating and emitting electromagnetic radiation of appropriate wavelengths, i.e. simulated missiles, that mimic real anti-aircraft missiles, and, in this way, the anti-aircraft missile launch warning and detection system (MLWDS) installed on aircrafts are deceived and the countermeasures are released. The operation of the counter countermeasures device and of the anti-aircraft weapon system, i.e. emitting of simulated missiles and launching of anti-aircraft missiles, is coordinated. The counter countermeasures device is implemented as a standalone device or is attached to or is integrated into the anti-aircraft weapon system. With the proposed air defense system and method, the efficiency of the anti-aircraft combat is highly improved, i.e. the probability of the target hit is highly improved.
