摘要
An anti-jam system for use with a normal L1 Only Global Positioning System (GPS) receiver. The anti-jam system includes a switchable L1/L2 RF downconverter for receiving L1 and L2 RF signals from an RF signal source and converting a selected one of the L1 or L2 RF signals to a low frequency analog signal. An analog-to-digital converter (ADC) converts the low frequency analog signal to a digital signal. A digital anti-jam processor processes the digital signal to enhance anti-jam performance. A digital-to-analog converter (DAC) converts the processed digital signal to an enhanced analog signal. An RF upconverter converts the enhanced analog signal to an L1-based RF signal for use by a normal L1 Only GPS receiver.
