Abstract
This paper presents a new analysis of a Rotman lens as an imaging processor. The modulation transfer function (MTF) has been calculated with the variation in the beam port spacing. The cutoff frequency is equal to the array size in λ. The beam port spacing should be narrow enough to avoid the aliasing.
