Summary:
A lens focused corrugated horn antenna has been designed and manufactured for use in a radar to detect land mines. A corrugated horn and a bifocal lens were designed so that it provides an appropriate beam spot size at a certain standoff distance from the antenna. Then, the antenna patterns were measured using the technique of modulated scatterers. An experimental model was developed to validate the antenna performances and the measurement technique. The measured patterns were in good agreement with the theoretically computed patterns.
