Anti-Jamming GPS Receiver With Reduced Phase Distortions
The ever-increasing reliance on Global Positioning System (GPS) and other Global Navigation Satellite Systems (GNSS) for navigation and guidance has created a growing awareness of the need for adequate protection against both unintentional and intentional jammers. Interference caused by jamming to the GPS signals can be mitigated by using adaptive signal processing,. In particular, adaptive array processing techniques allow exploitation of the spatial domain for improved jamming suppression and signal protection. An anti-jam GPS receiver is required to be operational at "Cold" start, i.e., to start with no information about its position and orientation.
