Abstract
A novel Ka-band two-channel correlation radiometer with independent local oscillator is constructed. To remain coherence in phase between two channels, the frequency of local oscillator must be very stable. The difference of phase between two channels, which is approximately invariable in a period of time, can be compensated by digital signal algorithm, so complexity of hardware can be reduced obviously.
