PURPOSE:To perform the regeneration of image data due to quick-look within a short time, by selectively using two radar systems using two kinds of Surface Acoustic Wave (SAW) dispersion type delay wires and two systems of band-pass filters. CONSTITUTION:Mixers 12, 14, 15, 16 are controlled by the gate signal from a control part 2 and charp pulses different in frequency and a pulse width are generated through two kinds of respective SAW delay wires 13, 16 to be transmitted from a transmission part 3 and reflected from the earth to be received and processed by a receiving part using two kinds of BPPs. If a system obtaining this desired resolving power and two radar systems enabled in the deterioration of distance resolving power at an early stage are used, it is unnecessary to deteriorate distance resolving power over a long time from a marked quantity of data of a radar system capable of obtaining the resolving power of one system and the regeneration of image data due to quick-look can be performed within a short time.
