Information on Radar Range Equation

The radar range equation (RRE) is an extremely important and useful expression for both designers and operators of radar systems. The RRE relates the range performance of a radar system to other radar components and their characteristics such as:
    

  • transmitter (transmitted power);

    •     
  • receiver (minimum detectable signal strength);

    •     
  • antenna (gain); and

    •     
  • target (radar cross-section [RCS]).

    •      In relating these characteristics to radar range, the radar range equation (RRE) provides an insight into the trade-offs and compromises that must go into designing and operating a radar system.
        
         The radar range equation is also important from an electronic warfare (EW) perspective. A derivative of the radar range equation is used in range calculations to determine the ability of electronic support (ES) to detect the radar. Electronic attack (EA) design considerations also rely on the same derivative to determine the range limitations of a given EA technique. The effectiveness of EA techniques can be calculated using the radar range equation and limitations of both the radar and the EW efforts can be determined.
