    Abstract
  • The physical optics (PO) and the method of equivalent currents (MEC) were used as the numerical computation method, and its feasibility was verified by experiment. A geometric model of conventional utility helicopter was established. Then its radar cross section(RCS)was calculated and analyzed. RCS reduction research was done by modifying the geometric shape and changing the number of rotating blades. The low observable shape of utility helicopter was put forward without large variation in static stability and available volume. The average RCS of the modified utility helicopter in forward (backward) and side direction is equivalent to 10%, 1% of the conventional one respectively. Rotating blades become the main radar scattering source of the modified helicopter, especially in the forward and backward direction. Some other methods are need to reduce the RCS further.
