摘要： PROBLEM TO BE SOLVED: To extract and remove a feature by use of image data and ground level surface layer data (altitude including the features), obtained by a synthetic aperture radar mounted in a mobile platform, such as an airplane and an artificial satellite, and create ground level altitude data (altitude excluding the features).
SOLUTION: A data storage 110 divides the image data and the ground level surface layer data into a plurality of cells and stores the intensity information of the image data and altitude information of the ground level surface layer data in every cell to a storage apparatus 190. A data selecting section 120 extracts the cells, having the intensities larger than a predetermined value or larger. A feature backside cell selecting section 130 refers to the imaging direction when the data is obtained, and selects feature backside cells. A feature cell creation section 140 creates the contour of the features, based on the cells extracted by the data selecting section 120 and the feature backside cells, selected by the feature backside cell selection section 130. A data replacement section 150 replaces the altitude data of the feature cells with the average of altitude data adjacent to the feature cells and creates the ground level altitude data.

摘要： PROBLEM TO BE SOLVED: To remove side lobe clutter to prevent a target range profile from deteriorating by actuating a clutter canceller when the electric power ratio target reflection wave computed from amplitude data input from a pre-amplitude detection circuit to side lobe clutter exceeds a fixed threshold value. SOLUTION: A pre-amplitude detection circuit 10 inputs output of a range pin selected by a range pin selecting circuit 9a, electric power of a target reflection wave is computed from a target range pin, the electric power of side lobe clutter is computed from range pins in front and rear of the target range pin, and both are fed as amplitude data to a control circuit 4a. The control circuit 4a computes the electric power ratio the target reflection wave to the side lobe clutter based on the input amplitude data, and when it exceeds a fixed threshold value, a clutter canceller 11 is actuated. The clutter canceller 11 is controlled by the center frequency of the side lobe clutter, and the side lobe clutter contained in the range pin output is removed.
