The Swedish Astor IV system is developed to manipulate radar signals, jam contemporary radars and deceive other electronic surveillance systems.
How radar jamming works
The Astor IV system manipulates the radar signal so that an enemy cannot detect a target. The system provides manipulated information so that it is not possible to identify whether a target exists at all or where it is located.
The system both receives and transmits tracking signals. An important component of the system is the DRFM unit (digital radio frequence memory) which can anticipate, modify and jam radar pulses. The system calculates speed, direction, angle and height in relation to the radar to be disrupted. The DRFM unit remembers the radar pulse which therefore easily manipulated or disrupted. In field tests, the system has proven to be very competitive and efficient compared to most qualified players internationally. Hardware and software in Astor’s system are proprietary. The group owns all IPR.
The system manipulates radar signals from ships, aircraft as well as stationary radar stations by receiving and transmitting signals.
