Abstract: A radar apparatus (1, 1', 1") and a leakage correction method thereof are provided. The radar apparatus (1, 1', 1") includes a transmitter (100, 100') and a receiver (200, 200', 200'-1, 200", 200"-1). The receiver (200, 200', 200'-1, 200", 200"-1) receives transmitting signals (TS) including a sinewave signal (SS1) from the transmitter (100, 100'). The sinewave signal generator (210, 210') of the receiver (200, 200', 200'-1, 200", 200"-1) generates another sinewave signal (SS2) according to the amplitude of the transmitting signals (TS) or received transmitting signals (RTS). The correcting circuit (250) corrects leakage situation (LS) on the received transmitting signals (RTS) according to another sinewave signal (SS2). The phasor of sinewave form corresponding to the leakage situation (LS) relates to the phasor of another sinewave signal (SS2). Accordingly, the performance of receiver (200, 200', 200'-1, 200", 200"-1) may be improved effectively.
