PROBLEM TO BE SOLVED: To provide a radar apparatus for detecting and tracking a very small target moving at a low speed with a high probability. SOLUTION: Single-direction multiple-hit data acquired by a low-speed-rotation antenna and a relatively high repetition frequency is constituted of the following signal processing processes: (1) a cumulative operation process, (2) an address conversion processing process, and (3) an addition processing process. Since integration between sweeps and integration between scans are effectively performed by the low-speed scanning of the antenna and the high repetition frequency, it is possible to detect and track the very small target moving at a low speed.
