RADARC Evaluation ROTHR Data: Winter, Spring, and Summer 1994.
Abstract
We find that the RADARC skywave radar estimation model in its simplest form provides received power level behavior that correlates well with observed received signal strengths from short to moderate one hop distances. Correspondence generally decreases with increasing range. Environmental noise from the model is similar to that observed. Spread in Doppler clutter (SDC), as an addition to the passive environmental noise level, frequently degrades performance. The RADARC version used did not predict the SDC observed, and the incorporation of a validated SDC model is where a major improvement in prediction can be implemented. The radar data we have used here employed a ten waveform repetition rate (WRF), and therefore indicated the performance to be expected when using the low WRF modes with no ambiguous range folding. However, although not exhibited in this study, we need improved very long range propagation predictions to account for ambiguous SDC.
