Signal Processing Techniques for Surveillance Radar Sets

One of the major recent advances in radar technology has been in the processing of the received signals. Several techniques have been developed to enhance the desired signals (aircraft) relative to ground clutter, sea clutter, rain, interference from other radars, and active countermeasures. The following techniques are discussed: MTI, Sweep Integration, and Blanking and Switching. A signal processing system utilizing these techniques is described.
