The British company BAE Systems for the ordering Agency defense advanced research of the USA have been developing new “smart” electronic warfare systems for combat aircraft. As reported by N+1 with reference to Flightglobal, the system will be self-learning and will be able to put interference-even promising radar with variable operating frequency.
Existing radars can only work in a fixed frequency band defined at the design stage. In order to prevent a radar to detect a target or to determine its exact coordinates, combat aircraft use electronic warfare systems, which pose interference.
Each such system has a built in database of working frequencies of existing radars. Upon detection of a radar signal, the system processes it, and compares with templates in the database. If the parameters of the received signal matches the pattern, the system puts the obstacle in accordance with the settings recorded in the database.
In the new system, developed under the project ARC (Adaptive Radar Countermeasures, adaptive combat radar) will be implemented machine learning algorithms with which it can adapt and develop new methods of anti-radar stations. In the first place with dynamic radar operating frequency.
The station probably will still use the built-in database for the analysis of the received signal. This will reduce the time required for the analysis of the received radar signal and setting the interference. A deep analysis and the ability to adapt to a new type of radar radiation will be produced, if the database fails to find a match.
Other details about the new electronic warfare system are not specified. In BAE Systems expect to receive the first working prototype of the ARC to the end of 2018. In 2019, the system should be ready for limited production.
In BAE Systems noted that ARC not developed for new aircraft and for existing. What exactly, is still unknown. Today the company supplies the station radioelektronnoi fight ALR-74 for the F-22 Raptor and the ASQ-239 to F-35 Lightning II. In addition, the modernized system EPAWSS British companies plan to install on the F-15E Strike Eagle and F-15C Eagle.
Meanwhile, the U.S. Navy conducted tests of electronic warfare systems of the new generation of NGJ. It will be installed on carrier-based electronic warfare aircraft EA-18G Growler instead of the legacy AN/ALQ-99. The radiation power of the new system is about 10.4 kW. It is able to automatically catch and process radio signals and to put the necessary interference.
As expected, the first set of NGJ will be adopted in 2021. The first operating version of the system will be able to “turn off” radar and communication systems operating at medium frequencies. It is, in particular, on the sighting of the radar. Later, you will add the possibility of jamming at low and high frequencies.
