Background radar systems are currently attracting attention due to the emergence of new problems to detection of small aerial objects. At the same time, reliable analysis and calculation of three-dimensional detection volume of aerial object using short-range background radar is lacking in the literature and therefore relevant. The paper considers the development of calculation theory of three-dimensional detection volume for monostatic pulse background radar taking into account different paths of illuminated and reflected from local objects pulse signal propagation, including the shadow component of the field scattered by aerial object, the coordinates of which are given in the three-dimensional region of space. The theory is developed for the pulse short-range background radar and an example is given of calculation of two-dimensional detection volume cross-section for arbitrary target height at change of mutual position of local objects relative to the background radar location point and coordinates of the aerial object, the shadow aperture of which is approximated by a rectangular cross-section. The proposed technique is applicable to the study and visualization of detection volume of drones and unmanned aerial vehicles by background radiation analysis methods when their geometric dimensions and three-dimensional coordinates of their mutual location relative to the background radar are changed.
