This paper demonstrates the concept of very long duration coherent integration to estimate the trajectory of a moving object using Global Navigation Satellite System (GNSS) passive radar. The theoretical framework of the concept is presented followed

To acquire a global navigation satellite system (GNSS) signal, the receiver must determine the Doppler offset experienced by the signal. The time and resources consumed in the Doppler search contribute to the cost and efficiency of the receiver, whic

GNSS receivers typically use closed loop tracking to receive and measure incident signals. In situations with high-dynamics, tracking may be aided by inertial or other external sensors to minimize tracking errors that would result in phase jitter. In

Modular system design offers several benefits such as flexibility, upgrade, extension and inter-operability across multiple vendors. The level of system modularity is strongly driven by design inter-dependencies. Several academic models have been pro

The detection of a desired weak GPS signal in the presence of other strong GPS signals is often problematic because the strong signal is not adequately attenuated by the receiver processing. The situation becomes worse in the case where multiple stro

Complex systems are distinguished by high-pleiotropy interactions where the effect of a change in one physical element ripples throughout the system. Previous studies on this subject conclude that system pleiotropy, which measures such inter-dependen
