Abstract

Microwave receivers play a critical role in Pulse Doppler radars, particularly in airborne radars and air surveillance; and are extremely versatile; therefore their analysis and conceptual design is an important issue. The receiver should have high dynamic range given that it is linked with a wide range of signals in Pulse repetition frequency Pulse radars in term of input power; but we cannot use Sensitivity Time Control (STC) or Automatic Gain Control (AGC). Therefore, the current paper provides a new conceptual structure that yields high dynamic range (over 100 dB).
