processing closer and closer to the antenna.For example, Figure 25.1 shows a simplified block diagram of the receiver front end of a typical radar system that would have been designed around 1990. Note that this system incorporated analog pulse compression (PC). It also included several stages ...
A digital radio frequency memory (DFRM) which converts an incoming analog radio frequency signal to a fourteen bit digital signal allowing for digital signal processing and then retransmitted as an analog RF signal. The DFRM provides a time delay for RF signals by storing the signal. The DFRM...
