A compact simulator for CNI RF environments

The authors describe the architecture, waveform simulation capabilities, and applications of an RF environment simulator capable of simulating up to 1000 simultaneous communication signals operating at frequencies from low HF to microwave. The simulator uses a modulator architecture and an innovative programmable emitter module to simulate a broad range of waveforms, signal structures, and platform dynamics effects in a compact physical size. The purpose of the simulator is to provide a test environment that adequately stresses the increasingly complex electronic warfare and communications, navigation, and identification (CNI) systems found on modern military platforms
