Radar Characteristics of Precipitation Affecting the Tracking of Ship’s Radar Objects
1 National University “Odessa Maritime Academy”, Odessa, Ukraine
ABSTRACT: In this paper, we consider the possibility of using the radar characteristics of precipitation in order to reduce the negative impact of the echo signal generated by them on the radar tracking of objects performed by the ship’s radar. In the formation of an echo signal by precipitation, both the precipitation particles themselves: their size, state (solid or liquid phase), shape, and the factors that determine their combined action (concentration, relative position, preferred orientation), are important. The size of rain particles when compared to the wavelength emitted by the ship's radar antenna contributes to the creation of a larger or smaller noise echo on the display of the ship's radar, the power of which in the Rayleigh scattering region toward the radar is characterized by the effective scattering area. Falling raindrops are a collection of randomly located reflectors and their scattering properties depend on the spatial distribution and regularity of movement. At the same time, the radar characteristics of clouds with precipitation generated by them can be used in ship radars to determine the intensity of the atmospheric process along the ship’s route, and the uncertainty in determining the attenuation of the power of an electromagnetic wave emitted by a ship’s radar antenna and passing through the precipitation zone can be reduced by simultaneous use of two wavelengths on which ship’s radars operate.
