An example method for enabling coherent reception of a radio signal includes, in some implementations, tuning a radio receiver to a first receiver frequency, generating within the radio receiver a test signal having a first test frequency, and measuring a first phase of the test signal while the radio receiver is tuned to the first receiver frequency. The example method also includes tuning the radio receiver to a second receiver frequency, which is different from the first receiver frequency, measuring a second phase of the test signal while the radio receiver is tuned to the second receiver frequency, and calculating a phase relationship depending on the first and second phases of the test signal. A radio receiver for coherent reception of a radio signal also is disclosed.
