Kalaetron RWR

Airborne radar warning receiver

The challenge

Existing and future threats require adaptive detection and classification capabilities so that mission and platform can obtain optimal protection.

In today’s electromagnetic spectrum, communication and radar signals from civilian and military applications can overlap. Detecting and locating objects correctly can be challenging due to wind turbines, active jamming and urban scenarios. Modern radar systems are extremely agile and use large frequency bands. Knowledge of radar-based threats gained during missions is not always available. The evaluation and availability of information gained from earlier and current missions is essential for the success of subsequent missions.

Challenges:

  • Dealing with unknown radar threats
  • Recognising radar signals in the frequency
    band of communication signals
  • Difficulty in recognising new radar threats
    with analogue systems
  • Enhanced lifetime of existing platforms
  • Network-centric operations
