| Abstract: | Early warning radars and searching radars of an air defense system must reconnoiter and detect the jamming signals instantly, which generated by hostile ECM forces, to take efficient electronic counter-countermeasures. Based on this point, a new kind of receiver named channelized receiver detecting jamming signals' spectrum is introduced. This receiver has the proprieties of instant, windband, high sensibility, and large lineal dynamic range. |
