The Research Of Hardware Design Methods For Anti-jamming Navigation Receiver

In order to adapt to different systems and applications, satellite navigation receivertechnology derived from different directions. In order to ensure the continuity andintegrity of navigation information, anti-jamming has become an important technicaldirection in navigation receiver technology development process.This paper introduces the basic hardware composition of anti-jamming satellitenavigation receiver. focusing on the design methods of RF channel and high precision ADconverter, and then design an appropriate hardware platform.For the RF channel part, How to improve the noise figure, dynamic range and bandrejection capability will be key. Relative to the current generic conventional designs, thispaper presents a method for improving the effectiveness of proceeds the IF frequency.For the AD conversion part, effective number of bits (ENOB) is the most importantdynamic parameter, and it best reflects the performance of the circuit. This paper describesthe meaning and test methods ENOB, and analyzes experimental results under variousconditions, which fully verified the performance of the hardware circuit and the validity ofthe methods used for its design.
