Abstract

Subject of Research.The paper deals with operating principles of optical pulse target seekers based on quadrant photodiode when targets are located in short-range field region. Method. Target image shape and light intensity distribution can affect static characteristics and cause appearance of image energy maximums when targets are located in short-range field region. Physical modeling of static characteristics plotting process was carried out. The main idea of the proposed method lies in counting sums of image pixels intensities in every virtual area of the sensor while virtual frame of the whole photodetector is moving over the target image. Main Results. Most probable target illumination directions were analyzed. Critical distances when the first extra image energy maximum appears were calculated for every target illumination directions. Time of missile uncontrollable flight at a near miss distance was also estimated. Practical Relevance. Research results point out that using of control loop proper logic is required to provide reliable target shot down for active and semi-active laser homing systems. Also disabling of such systems should be carried out when targets are located in short-range field region.


Keywords: target seeker, static characteristic, quadrant photodiode, automatic homing, tracking loss
