In modern radars, the design is such that radar vulnerability to noise disturbance is significantly reduced. This dramatic decrease is due to the fact that radars are always trying to increase their capability against the heavy clutter they receive from the ground. Radars use antenna sidelobes to reduce clutter. By reducing the antenna sidelobes, the vulnerability of the radar to the heavy clutches of the sidelobes is reduced, which also reduces the vulnerability to sidelobe disturbance. In this article, we try to examine the reduction of clutter causing the reduction of vulnerability to disorder. تفاصيل المقالة
