In a method of designing the transmission power of a synthetic aperture radar installed on a flight object such as an artificial satellite, the transmission power is designed such that, in applying radar equation Pr=Ptx sigma xAp2/(4 pi lambda 2R4) [Pt:transmission power (W), sigma : radar scattering cross section (m2), Ap:antenna area (m2), R: distance to the object to be observed (m), lambda : wavelength of radio wave (m)] for setting transmission power Pr so as to satisfy the conditions required for the radar, the radar scattering cross section sigma is set to sigma = sigma 0xS2x4 pi / lambda 2 [ sigma 0:scattering coefficient, S:area of irradiated domain (m2)].
