We describe a sensing scheme that, by designing a transmitter array and a single receiver antenna, potentially resolves the low-power limitation that has plagued previous quantum illumination protocols. Despite the interference among different returning signals, we provide two measurement protocols, one based on parametric amplification, and one based on the recently proposed correlation-to-displacement conversion to achieve a quantum advantage in multiparameter estimation and hypothesis testing.
