RADAR CROSS SECTION PREDICTION FOR DIFFERENT OBJECTS USING MAT LAB AND RADAR CROSS SECTION (RCS) REDUCTION

Radar Cross Section (RCS) depends on the characteristic dimensions of the object compared to the radar wave length. The Radar Cross Section of the target determines the power density returned to the radar for a particular power density incident on the target. The cross section is more dependent on the target shape than its physical size. The radar antenna captures a portion of echo energy incident on it. Radar Cross Section fluctuates as a function of radar aspect angle and frequency.Using the MAT LAB Programming, Prediction of Radar cross section `σ`  for simple shapes of targets like Sphere, Ellipsoid and Circular Flat Plate. The methods of controlling radar cross section and penalties of implementing these methods are discussed. The four basic techniques for reducing radar cross section (target shaping, radar absorbing materials, passive cancellation, and active cancellation) are summarized with their advantages and disadvantages.
