The e-book units out to provide an explanation for the fundamental rules of radar and, the place appropriate, historic elements of the evolution of those rules are handled. The learn, whereas underlining the importance of the hollow space magnetron, purposely restricts itself to the pre-cavity magnetron period of radar.

7. The radio frequency (RF) amplifier stages occurred in early metric equipments, but later, in the first microwave sets, the signal generally went straight from the antenna into a crystal mixer. One reason for this was that available microwave amplifiers were noisy. With the advent of low noise parametric amplifiers, RF amplifier stages have reappeared in microwave receivers. Most radar receivers are, and have been, of the superheterodyne type. The principal aims in receiver design were a low noise 'front end', a * GEMA = Gessellschaft fur Elektroakustische und Mechanische Apparate.
