Research on a Digital Channelized IFM Receiver
Zeng‐Ping Chen · Radar Science and Technology · 2012
In order to receive wideband signals,an efficient architecture of digital channelized receiver with the property of high decimation factor is devised in this paper.Furthermore,digital signal detection and instantaneous frequency measurement(IFM) technologies are applied to this architecture and the requirement for using IFM technology is acquired.A new kind of filterbank that can deal with the cross-channel signal by pass-band overlap when the bandwidth of signal is narrow is also proposed.The simulation results show the effectiveness of the new structure and verify the correctness of the new filterbank when dealing with the cross-channel signals.
