A method of measuring the electron cyclotron radiation from plasmas by using confocal resonant cavity and sweep frequency receiver is proposed. A radiation spectrum expression for a uniform plasma slab in the confocal resonant cavity has been derived. The analysis shows this method can independently measure TOKAMAK's electron temperature and its radial distribution. Furthermore, as a quasi-optical receiving system, it possesses high spatial resolution power.
