Abstract :
The effect of thermal lens losses on the sensitivity of radar systems is described in connection with optimizing the maximum free-space range. A mathematical approach has been developed for estimating the decrease in the sensitivity of the radar system for designed maximum radar range. The variation of range reduction with thermal lens loss for different values of surface refractivity is explained.<>
