Coherent detection meaning
WebA Coherent Processing Interval (CPI), in radar systems, indicates a group of multiple pulses, usually with the same PRF and frequency. A CPI will generally consist of one or more coherently integrated pulses, and possibly 1 or more fill pulses. What is integrator in coherent detection? WebIn the transmitter of a communications carrier system, a carrier wave is modulated by a baseband signal. At the receiver, the baseband information is extracted from the incoming modulated waveform. In an ideal communications system, the carrier signal oscillators of the transmitter and receiver would be perfectly matched in frequency and phase, thereby …
