Electronic Support Measures (ESM), Electronic Counter Measures (ECM), Electronic Warfare (EW) and Software Defined Radio (SDR) comprise the interception and analysis of radio signals from often unknown sources. Key questions which need to be answered are about the source of the signal (friend or foe) and the location of the transmitter. The key to answering these questions is by determining the protocols, coding and waveforms, as well as the locations of the radio stations and other information about the source. This is done by a channelizer.
A channelizer extracts channels from the received RF-band for follow-on baseband processing, and, in the case of SDR, also inserts channels into the RF band for transmission.
Typically, the architecture of a channelizer consists of an analog front-end, which captures the signal from the radio spectrum. Subsequently, this signal is digitized and processed. User specific algorithms may be applied in a final step to distill the relevant information from the abundance of data captured at the front end.
