RADAR APPARATUS AND LEAKAGE CORRECTION METHOD
First Claim
1. A radar apparatus, comprising:
- a transmitter, comprising;
a first sinewave signal generator, configured to generate a first sinewave signal; and
a receiver, configured to receive a transmitting signal transmitted by the transmitter, wherein the transmitting signal comprises the first sinewave signal, and the receiver comprises;
a second sinewave signal generator, configured to generate a second sinewave signal according to an amplitude of the transmitting signal or an amplitude of a received transmitting signal; and
a correcting circuit, coupled to the second sinewave signal generator, and configured to correct a leakage situation of the received transmitting signal based on the second sinewave signal, wherein a phasor corresponding to the leakage situation in a sinewave form is related to a phasor of the second sinewave signal.

Abstract
A radar apparatus and a leakage correction method thereof are provided. The radar apparatus includes a transmitter and a receiver. The transmitter includes a sinewave signal generator. The sinewave signal generator generates a sinewave signal. The receiver includes another sinewave signal generator and a correcting circuit. The receiver receives transmitting signals including the sinewave signal from the transmitter. The sinewave signal generator of the receiver generates another sinewave signal according to the amplitude of the transmitting signals or received transmitting signals. The correcting circuit corrects leakage situation on the received transmitting signals according to another sinewave signal. The phasor of sinewave form corresponding to the leakage situation relates to the phasor of another sinewave signal. Accordingly, the performance of receiver may be improved effectively.
