Civil aviation in under increasing danger of malicious or erratic disturbances. Jamming or ghost targets may appear, caused by criminal attempts of disturbances, but also by malfunctioning devices, e.g., other radars or civilians, experimenting illegally with amplified radiation sources. ATCOs need to be able to distinguish between real targets and the fake signals. They need to find ways to reestablish the security of the FIR, without endangering the safety of people in the air and on the ground. SkyRadar's Target Generator has been developed to be used in conjunction with the SkyRadar FMCW, to prepare ATCOs and ATSEPs on such situations.
This product has been developed purely for civil purposes. However, as it may be used in a limited way for military-oriented ECCM training, export outside Europe and Northern America may be subject to a prior release by the German
Federal Office of Economic Affairs and Export Control.
The FMCW target generator operates with one patch antenna. It consists of a measuring system to analyze the frequency modulation of the targeted radar and of a target generator to jam the radar with artificial targets. The target generator is placed on a static tripod.
A comfortable GUI allows for easy operations with only short familiarization
This subsystem may be used for measuring RF characteristics of K-band receivers, transmitters and transceivers. It sends a programmable, highly stable carrier frequency from 23...25GHz to a 4x4 path array antenna.
At the same time, the RF generator is used as LO for the receiver.
The receiver part allows measuring incoming RF power at a separate patch antenna. It also delivers signals for a high precision frequency determination of the incoming RF signal.
This subsystem simulates a moving object generating a stereo doppler signal.
It receives the 24GHz carrier signal of a K-band doppler module and sends back a signal corresponding to an approaching target with a programmable frequency of -9999Hz to 9999Hz, where the sign simulates the direction of the target.
Graphical User Interface
The target generator comes with a state-of-the art office type Laptop computer, allowing for control of the system and for visualization.
