Exploiting Spatial and Doppler nulls is a straightforward way to construct a valid blocking matrix(BM) in the generalized sidelobe canceller(GSC)-based Space-time adaptive processing(STAP). However, spatial nulls of the airborne collocated MIMO radar are not uniformly distributed and their unknown frequencies remain to be estimated. In this work, we develop estimation rules of spatial null for the...Show More
In this paper, the radiation physics of edge-coupled connector is investigated with sub-structure characteristic modes and the current on the signal traces of different wafers is identified as the trouble maker for the final electromagnetic interference.Show More
