Conversely and wave

Conversely, a high PRR / PRF can enhance target discrimination of nearer objects such as a periscope or fast moving missile leading to practices of employing low PRRs for search radar, and very high PRFs for fire control radars, with many dual-purpose and navigation radars, especially naval designs having variable PRRs which might allow a skilled operator to also use a PRR adjustment to enhance and clarify a unclear radar picture, for example in bad sea states where wave action generates false returns, and in general for less clutter, or perhaps a better return signal off a prominent landscape feature ( e. g. a cliff ).
Conversely, a system which changes the shape of the wave ( beyond simple scaling or shifting ) creates additional harmonics ( harmonic distortion ).
