HOLOGRAPHIC OBJECT DETECTION

摘要

PURPOSE:To conduct object detection with high resolution in the bearing and distance without depending on the detected distance by processing a hologram data obtained from received reflection waves, using specified test functions. CONSTITUTION:Received wave reflection data from an object by means of a transmission wave with many frequency components from each measurement point, as an anthena 2 mounted on an anthena transferring device 9 and a received wave transmitting device 3 move, is supplied to an accumulation device 6 through an A/D converter 4, a specified digital filter 5 with the measurement point location data through a position measurement device 7 and an A/D converter 8. The hologram data based on those received wave data is processed by an integrator 11 to which the test function from a function generating device 10 by which an image amplitude function becomes maximum that is defined by taking as variables the space coordinates between the test function of a function of two variables representing a position on a plane and a time variable and a received wave shape function. In this way the image regeneration is made by the image regeneration argonism based on pulse compression and aperture composition by clear formulation of the wave shapes reflected from the object.
