A high frequency surface-wave (HFSW) overthe- horizon (OTH) radar is often required to detect targets against a mixture of clutter and interference-plus-noise. Conventional (FFT-based) Doppler processing improves target detection by separating targets and clutter into different Doppler frequency bins and providing coherent gain on targets against interference-plus-noise. In the high frequency (HF) band (3-30 MHz), the combined clutter and interference-plus-noise disturbance can be highly structured in the time domain (i.e. from pulse-to-pulse) within the coherent processing interval (CPI). In this work, we propose an adaptive Doppler processing method based on the Generalized Likelihood Ratio Test (GLRT) that exploits this structure to enhance target detection. In particular, we present the first experimental results for this class of detector in a HFSW radar Doppler processing application.
