Abstract:	In this paper, we describe a methodology for evaluating digital receiver architectures for GPS anti-jam applications. In addition, we outline specific performance trade-offs that are necessary in designing high jamming-to- signal ratio (J/S) GPS receivers. Given a set of user requirements and platform constraints (e.g., J/S, size, weight, and power), a system designer may employ the methodology to quickly determine system and component-level requirements. This will help the designer to identify A/J receiver vulnerabilities, determine key receiver performance limitations, predict implementation feasibility, and recommend specific RF (radio frequency) and ADC (analog-to-digital converter) technology developments to support future system requirements. Based on the methodology presented an RF-to-digital translator that provides 97 dB J/S without automatic gain control (AGC) has been designed. The translator can be used in either single-channel (e.g., ground-based applications) or multiple-channel (e.g., airborne phased-array applications) configurations.
