noise radar systems encounter target fluctuation behavior similar to that of conventional systems. For noise radar systems, however, the fluctuations are not only dictated by target composition and geometry, but also by the non-uniform power envelope of their random transmit signals. This third dependency is of interest and serves as the basis for the preliminary analysis conducted in this manuscript. General conclusions are drawn on the implications of having a random power envelope and the impacts it could have on both the transmit and receive processes. Using an advanced pulse compression noise (APCN) radar waveform as the constituent signal, a computer simulation aids in quantifying potential losses and the impacts they might have on the detection performance of a real radar system.

Experimental results from recent field testing with the noise correlation radar (NCR) are presented as a proof of concept. In order to understand the effectiveness of the NCR, a pre-determined set of measures is established. We discuss the three experimental configurations used in evaluating the system's range resolution/error, robustness to interference, and secure radio frequency (RF) emission. We show that the advanced pulse compression noise (APCN) radar waveform has low range measurement error, is robust to interference, and is spectrally non-deterministic. In addition, we determine that an improvement in range resolution due to phase modulation is achieved as a function of the random code length rather than the compressed pulse length.
