Abstract [en]

Adaptive skywave estimation techniques that can monitor the delays and strengths of skywave components in real time are desirable in Loran-C receivers since they allow optimal sampling points to be selected. Such techniques should enable the receiver to minimize the errors due to skywave interference while maximizing signal-to-noise and signal-to-interference ratios. This paper reports on novel signal processing techniques employing classical Fourier analysis and modern high-resolution algorithms for identifying skywaves and measuring their delays. The benefits of these methods are assessed, together with the cost in computing resources of implementing them in receivers. The paper includes theoretical analysis, computer simulations, and the results of tests using off-air signals. A prototype Loran-C system employing the proposed techniques is described
