ABSTRACT:
An instantaneous frequency measurement receiver (IFM) is used at each output of a digital channelized receiver. A Fast Frequency Transform (FFT) is used to form an instantaneous frequency measurement (IFM) receiver at every frequency component. These IFM receivers can perform frequency coding and produce fine frequency measurement.
