Abstract

PURPOSE:To generate a standard reception signal of a synthesized aperture radar simply, by making convolutional integration and processing of addition for imaginary and real parts of a complex transmission pattern written in an RAM with imaginary and real parts of a transmission signal. CONSTITUTION:A complex transmission pattern P(u) of a synthesized aperture radar from an external storage device 8 via a control section 12 is written in an internal RAM 10. Real and imaginary parts of the pattern P(u) from the RAM 10 are processed at A/D converters 11a, 11b and LPFs 13a, 13b, and digital values PI(u), PQ(u) are respectively applied to convolutional integrators 4a, 4b. They are processed for convolutional integration with real and imaginary parts TI(t), TQ(t) of a complex transmission signal T(t) of the synthesized aperture radar processed at a distributor 2 and 90 deg. phase shifter 3. The integration value is added at a magic T5, a standard reception signal V(t) is simply generated with the operation based on equation, allowing to perform system verification of the synthesized aperture radar.
