Direct position determination (DPD) was recently proposed as a new method for passive localization of narrowband radio transmitters. Its superior performance, especially in the low signal-to-noise ratio (SNR) regime, is ascribed to both the joint optimization it performs over all base stations that participate in the estimation process and the direct determination of the emitter position as opposed to conventional methods which typically process the information from the individual base stations separately and determine the location using two estimation steps. In this paper, we introduce the cyclic direct position determination (CDPD) algorithm, a novel method which is the cyclostationary counterpart of the DPD. Despite its name, the CDPD is not a simple extension of the DPD but a unique algorithm which deviates substantially from its ancestor. Yet, the CDPD enjoys both the benefits of the DPD algorithm and the great performance robustness in the presence of narrowband interferences thanks to its cyclostationarity exploitation.
