Section 1
CHAPTER 5
Basic outline of CW radar
about the operation of radar circuits and components. Further details of c.w. radar will therefore be found in Section 7.
It should be noted that the frequency of received pulses in a pulsed radar is also altered by Doppler shift. However, the Doppler shift is small and in a pulsed radar is accepted within the bandwidth of the receiver circuits. In a Doppler radar the shift frequency is the important factor and to ensure accuracy the frequency stability of a Doppler radar must be high.
This concludes the first section of this book. The aim was to show the basic principles of radar and its limitations and applications. Having learned how basic systems operate at block level we must now proceed to 'look inside' the various boxes to see what they contain and how they function to provide the outputs we need. This is done in succeeding sections.
