Measurement system and method for cancelling image portions

Abstract

The present invention generally relates to a measurement system and method for eliminating image portions. The measurement system includes a narrowband receiver configured to receive an input signal having an initial bandwidth. The narrowband receiver includes at least one local oscillator configured to provide a local oscillator signal having a center frequency, and at least one signal mixer configured to mix an input signal and the local oscillator signal to obtain a mixed signal including an image portion. The mixed signal has a respective center frequency in view of the local oscillator signal in which it is mixed. The narrowband receiver is configured to process the two or more mixed signals to obtain two or more captured signals for different center frequencies of the local oscillator signal. The two or more captured signals have a limited bandwidth compared to the initial bandwidth. The narrowband receiver is configured to combine the two or more captured signals in order to obtain a processed signal without an image portion.
