Passive Millimeter-Wave Radiation Characteristic Analysis of Kelvin Wake

Passive millimeter-wave (PMMW) radiation of Kelvin wake is helpful for ship detection. A local coordinate system is established at each small facet to calculate the brightness temperature of Kelvin Wake. The influence of ship speed and draft on brightness temperature of Kelvin wake is simulated. An outdoor experiment was conducted to measure the brightness temperature of Kelvin wake. The experiment result verifies the theory and simulation.
