The atmosphere, acting like a lens, causes a small loss in radarsignal strength [1]. Unlike atmospheric absorption [2], the lenseffect loss is different for distributed targets versus point targets.For a distributed target uniformly filling the radar beam, the lens effect loss (in decibels) is one-half the lens-effect loss for point targets.
