Software Defined Radio for Link Diversity

Objective: Design and develop an agile software defined radio (SDR) system capable of supporting multi-band communications with advanced frequency management for interceptor platforms. Description: This topic seeks to design and develop an SDR featuring multi-band operation, advanced frequency management, and enhanced processing capabilities. The program desires to create drop-in, or near drop-in replacements of existing radio systems to enhance communication capabilities of interceptors across S, X, and Ka bands. The radio must feature independent RF chains capable of rapid frequency hopping, adaptive frequency selection based on signal-to-noise ratio (SNR) and make-before-break handover mechanisms. The system shall incorporate temperature-controlled crystal oscillation for precise timing and demonstrate the ability to continuously sense, rank order, and schedule frequencies within specified bands. The radio must be survivable against the austere environments of interceptor flight while maintaining simultaneous communications with ground and space assets. Specific communication bands and performance metrics will be provided after award. Keywords: Software Defined Radio; Multi-band Communications; Frequency Agility; Link Diversity CMMC Level: Level 1
