The electronic countermeasure system uses the ARW9101 radar alarm, with a frequency range of 0.7~40,000Hz, covering almost all frequencies of the existing airborne fire control radar. The sensitivity can reach 85 decibels, and the database can store 100 radar models of signals. When the aircraft is threatened by the other party's radar, the system can provide warning symbols and sound warning signals to the pilot on the flat display or cockpit electronic display, and can automatically or manually drop foil strips and infrared jamming bombs
