| Popis: | International audience; Passive radar systems generally receive direct path, ground echoes and potential target echoes. As the first two are much more powerful than the target signals, they have to be rejected. Numerous solutions are proposed in the literature. The algorithm introduced by [1] has become a reference. Due to the airborne passive clutter spread, this algorithm faces limits. In this article, we derive two solutions in order to be able to reject a large amount of clutter and therefore to reduce detrimental secondary sidelobes. Experimental results prove that the proposed method performs only 4 dB worse than in a ground configuration. |
