摘要：
A Software Defined Radio (SDR) allows a single hardware platform to be reconfigurable so that it can accommodate multiple radio waveforms and be easily upgraded with software changes. The joint Tactical Radio System (JTRS) is the Department of Defense's (DoD) solution for a family of tactical SDRs based on common open standards and architectures. JTRS accommodates legacy and new mobile ad hoc networking waveforms. Additionally, military Satellite Communication, and Intelligence, Surveillance, and Reconnaissance (ISR) terminals are migrating to SDRs to enable consolidation of multi-ple legacy systems into single multi-band configurations. This article describes current military SDR programs, their challenges, and the way ahead for the DoD.
