Simulations based on real-life FM radio waveforms showed that the algorithm is capable of improving range resolution, and thus the accuracy, according to theory for single scatterers as is summarized. The performance of the algorithm was impacted by the fluctuating behavior of the FM radio signal, although less than expected. The simulations also showed that two targets, not resolved in the individual channels, are resolved by using the proposed algorithm properly. Single scatterer targets may be significantly better positioned by the improved resolution (and as a consequence, also the accuracy) capabilities, i.e., 10 times the best performing individual channel.
