The 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 provides an insight into the trade-offs and
compromises that must go into designing and operating a radar
system.
The RRE 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
RRE and limitations of both the radar
and the EW efforts can be determined.
