  • Radar system
    Patent number: 5731780
    Abstract: Radar system for the generation of two-dimensional or three-dimensional position indications of targets. Three-dimensional position indications are obtained by periodically canting the antenna about a canting axis, such that the antenna beam plane makes an angle with a normal on the earth's surface and by combining azimuth data and range data obtained at different canting angles. For a radar system provided with dual-axis stabilization means, these means may also provide for the canting of the antenna means.
