Keystone transform

Lagrange polynomial interpolation based Keystone transform for passive radar

In this paper we address the problem of target’s range migration in passive bistatic radar exploiting long coherent integration times with fairly wideband signals of opportunity. We resort to the well-known Keystone Transform (KT) to compensate for the range walk effect and to take advantage of a higher coherent integration gain against targets with non-negligible radial velocity.
