    Abstract
  • If several interferences (including broadband and narrowband) appear o r satellite signal and interference have similar direction of arrival, the locat ion precision decreases below the normal level required in satellite navigation receiver. Therefor a constrained space-time adaptive processing(STAP) approach was propos ed to ensure low suppression of satellite signal which is direction si milar with interference by obtaining direction information of satellite and inte rference as constraint ahead. Simulation suggestes that it maintains high inter ference suppression degree (above 40dB), increases suppression freedom of degree , and ensures the normal reception of satellite signal while satellite and interf erence are direction similar (almost 10°). The method can increase the anti-ja mming ability of the regional satellite navigation receiver in complex electrica l surroundings.
