In this paper we propose a new detector called the gamma constant false alarm rate (gamma CFAR). The gamma CFAR detector utilizes a family of gamma functions which provide the ability to change the scale and shape of a stencil that models the local area in an image. The scale and shape can be selected adaptively after training in a way so as to give minimum false alarms. The detector makes the maximal use of intensity information to discriminate targets from background clutter. A significant increase in the signal-to-noise ratio is observed.
