Interferometer-type radar

An interferometer-type radar comprising:

• a transmitter for transmitting a signal to a target;
• and
• a receiver for receiving a reflection signal reflected from the target, wherein
• the transmitter has a function of outputting a FMCW signal for detecting
• and velocity of the target from a transmitting antenna, and
• the receiver has:
• a function of receiving a reflection signal reflected from the target with a plurality of receiving antennas at a same time as transmitting from the transmitter, performing spectral analysis with respect to receiving signals which are frequency-converted with a signal same as a transmitting signal of FMCW, and classifying the receiving signals by distance component;
• a function of performing correlation processing between signals of receiving antenna systems;
• a function of integrating signals which have been correlation-processed;
• and a function of performing two-dimensional FFT to an output which has been integration-processed and measuring the direction and the velocity of the target.

An interferometer-type radar comprising:

• a transmitter for transmitting a signal which is changed by a constant frequency change rate k and repeated in a cycle T;
• a receiver having a heterodyne function in which a signal reflected from a target is frequency-converted with a local origination signal, of a timing completely same as a transmitting signal or a timing which is phase-synchronized, which is changed by a frequency change rate k and repeated in a cycle T;
• and
• an A/D converter for digitizing with a sample frequency F (F=kT) which is a product of the k and T.
