Efficient Channelized Technology Based on Filter Banks

With the appearance of novel low probability of intercept, the bandwidth of radar is wider and wider. Wideband digital receiver becomes a research hotspot in the field of communication, radar and electronic reconnaissance, etc. As one of many systems of wideband digital receiver, digital channelized receiver has become research emphasis due to the characteristics of full probability receiving and processing multiple signals. Digital channelized technology and signal sampling theory are deeply studied and an efficient channelized model is derived and given based on filter banks. The correctness of the model is verified by computer simulation. The model has less computation compared with traditional model, which is suitable for engineering application.
