Abstract
An apparatus is disclosed for detecting the shape of an object by means of radar. A transmitter 1 forms signal units wherein the transmitting frequency is varied continuously and linearly within a predetermined frequency bandwidth. By repeating this signal unit at fixed periods, a transmitting signal having a continuous waveform is generated. A receiver 5 detects signals reflected from a target 11, and converts them to video signals. An A/D converter 6 samples these video signals and digitizes them. The digitized video signals are stored in a first two-dimensional memory 7 according to a transmitting frequency index and a transmitting period index. A range compression device 8 resolves sequences of these digital video signals in a range direction by performing an inverse Fourier transformation on columns of data stored in the memory 7 which have the same transmission period. A cross-range compression device 10 resolves sequences of these digital signals in a cross-range direction by performing a Fourier transformation on rows of digital video signals which have the same range.
