Basic Radar System Block Diagram consists of a transmitter and a receiver each connected to a directional antenna. In this chapter let us discuss the working of Pulse Radar. The output of the mixer is applied to the IF amplifier stages. All frequencies and clock pulses are derived from the highly stable frequency of a master oscillator and these signals therefore have a phase reference stable to each other. A typical superheterodyne radar receiver is shown in figure 2-23. The diagram illustrates a full transfer plus the start of the next transfer.
