An Analysis of X-Band Calibrated Sea Clutter and Small Boat Reflectivity at Medium-to-Low Grazing Angles

[摘要] The coherent temporal characteristics of medium-to-low grazing angle sea clutter and small boat reflectivityare considered for different radar waveforms under a rangeof environmental conditions and geometrical configurations. Accurateempirical modelling of sea clutter enables the inferenceof the local sea conditions from radar returns, pertinent forport safety and navigation. Understanding the dynamics andassociated reflectivity of small boats, in addition to empiricalsea clutter models, allows the development of advanced detectionand tracking algorithms, which will improve the performance ofsurveillance and marine navigation radar against small boats.Work presented is based on the empirical analysis of datarecorded with two calibrated, coherent, pulsed radar systems atX-band frequencies. Specifically, target echoes from small boatsare included in the datasets and subsequent analysis.
