A new transportable precision approach radar

The monopulse technique is widely used for tracking radars. For tracking at a low elevation angle, a narrow beam is required in the elevation plane to reduce multipath signals such as ground reflections. In this case, an elliptical aperture is desired. The authors have developed a new transportable precision approach radar for a radar approach control using a phased array antenna with high tracking accuracy and aperture efficiency which is composed of a monopulse feed and an elliptical aperture. The authors outline the radar system
