<p>PURPOSE:To improve horizontal and vertical resolutions by forming a hyperbolic distribution pattern based on the target reflection in a reflection echo, distributing the pattern into areas and subdividing it, and performing composite aperture processing. CONSTITUTION:A pulse radio wave is radiated into the ground and the hyperbolic distribution pattern is formed based on the target reflection in the reflection echo from a target. The condition of the ground is calculated from the intensity of the reflection echo and the hyperbolic distribution pattern is divided into areas according to a level value based on the calculated condition of the ground. The pattern diagram of the area-divided hyperbolic distribution pattern is subdivided and the composited opening processing is performed based on the subdivided hyperbolic distribution pattern.</p> |
