GPS Rectangular Planar Array Design Based on Sidelobe Constraints and Quadratic Null Constraints

In order to suppress mass low power jamming and some high power jamming in GPS receiver; GPS planar array combined sidelobe constraints and quadratic null constraints is designed; sidelobe constraints can suppress low power jamming, quadratic null constraints can suppress high power jamming; computer simulation results show that this design can restrain concealed jamming from sidelobe at controlled level and generate larger and deeper null than simple null at strong jamming direction; this design is very suit for array design of the GPS anti-jamming receiver.
