| Abstract: | The adaptive sidelobe cancelling(ASLC) is an effective measure against active jamming. Beam pattern null in the direction of jamming is formed by space filtering and assistant receive channels to restrain the jamming.The basic theory of the adaptive sidelobe cancelling is introduced in this paper. And then,its hardware realization based on FPGA is given.Finally, its performances are analysed using MATLAB simulation and experiment results. |
| Keywords: | adaptive sidelobe cancelling(ASLC) field-programmable gate array(FPGA) space filtering active jamming beam pattern |
