A METHOD AND APPARATUS TO IMPROVE ANTI-JAMMING AND TO ELIMINATE JAMMING IN A GPS SYSTEM BY ADJUSTING ADDITIONAL THRESHOLD VALUE IN THE FREQUENCY DOMAIN

摘要

PURPOSE: A threshold weighting factor control method is provided to reduce jamming influence by applying a threshold determination algorithm. CONSTITUTION: A receiving antenna(1100) receives a signal. An RF/IF translator(1200) changes a signal received from the receiving antenna. A jamming eliminator(1400) uses the transformed signal and processes a signal with a K-median threshold control method.
