A radar imaging apparatus includes: (i) a delay code generation unit which repeats, for M scan periods, scan processing of generating, using a transmission code, N delay codes in a scan period for scanning N range gates having mutually different distances from the radar imaging apparatus; (ii) a signal storage unit which stores, in association with a range gate and a scan period, a baseband signal; (iii) a memory control unit which repeatedly writes, in the signal storage unit, for the M scan periods, N demodulated signals corresponding to a single scan period, and reads out a group of M demodulated signals corresponding to mutually different scan periods; (iv) a Doppler frequency discrimination unit which performs frequency analysis on demodulated signals having the same range gate; and (v) a direction of arrival calculation unit which estimates a direction of a target.

Radar imaging apparatus, imaging method, and program thereof

A shape measurement instrument includes a plurality of transmitterstowhich radiate signals having different waveforms or phases, receiverstowhich receive signals reflected from an object O, correlation unitstowhich obtain correlation waveforms between waveforms of the signals received by the receiversto, and the signal radiated by a transmitter radiating the received signal of the transmittersto, and a shape estimation unitwhich extracts a quasi-wavefront based on the correlation waveforms obtained by the correlation unitstoand estimates a shape of the object O based on a relationship between the quasi-wavefront and the object O. As a result, a period of time required to measure an object shape can be significantly reduced.
