Zusammenfassung:	PURPOSE:To exclude erroneous discrimination caused by cloud and sea clutters, by detecting the horizon from a searching scene, and extracting a searching object in the vicinity thereof as a real object. CONSTITUTION:When a searching scene is stored in frame memory 10, an image at every frame is scanned along each vertical line by a differentiation circuit 13 and a large differentiated value is outputted to an integration circuit 14 at the horizon part. In the integration circuit 14, a sum is calculated at every horizon and the horizon proposed showing the max. integrated value in each frame is selected in a horizon detecting circuit 15. The estimate horizon is calculated with due regard to a weather condition and a flight in a linear regression operation circuit 16 and only an object present in the vicinity of the estimate horizon in object information, which is preliminarily imparted from an object detecting circuit 11, is set as a real object in an object discriminating circuit 12.
