Abstract:

The technique of calculation of near-zone electromagnetic fields scattered by complex shape airborne objects is present. It is shown that the direction line defined by a direction finder differs from true one and depends on geometry of the object, its electrical sizes and also on mutual location of the transmitting antenna, object and receiving antenna. The results of numerical calculations for the object such as airplane are represented. Calculation was carried out in a centimeter band, separately in a plane of course and pitches one, radiation - monochromatic. The angle of object elevation is constant and it is equal to three degrees.
