Analysis of symbol-design strategies for intrapulse radar-embedded communications

The design of communication symbols that may be embedded on an intrapulse basis into the backscatter generated by a high-power, pulsed radar is considered. This framework requires the asynchronous detection of transmitted symbols in a high-interference environment that degrades the capabilities of conventional intercept receivers. The impact of symbol design and filter structure upon the successful detection of covert symbols by the intended receiver and a hypothetical partially clairvoyant intercept receiver is examined.
