Beschreibung
Zusammenfassung:	A radar apparatus configured to prevent a harmonic generated by a limiter from being transmitted outside is provided. The radar apparatus includes a harmonic processor between a circulator and a limiter. The harmonic processor includes harmonic processing stubs, and a compensation stub. The harmonic processing stubs attenuate the harmonic which is generated when the limiter attenuates a transmission signal passed through the circulator. The compensation stub cancels a change of a susceptance caused by disposing the harmonic processing stubs.
