Embodiment Construction

[0019] like figure 1 , 2 The shown microwave scatterometer inversion oil film thickness device includes a microwave scatter transmitter 1 for transmitting microwave pulses to the surface of a target object, a microwave scatter receiver 2 for receiving scattered light from the target object surface, and a microwave scatter receiver 2 for analyzing The network instrument 3 scatters the scattered light received by the receiver 2 . After the network instrument 3 receives the scattered light, the digital signal processor 7 and the ADS software 8 are used to jointly analyze the spectral characteristics and invert the scattering spectral curve. Inversion of oil film thickness using scattering spectrum curve and scattering electromagnetic model.

[0020] When the ship travels to the oil spill site, the slide rail support 21 is fixed to the hull, and the instrument is moved to the outside of the hull through the slide rail 20 for measurement. Turn on the microwave scatter transmitt...

Abstract

The invention discloses an oil film thickness inversion device of a ship borne microwave scatterometer. The device comprises a microwave scattering transmitter, a microwave scattering receiver and a net device, wherein the microwave scattering transmitter transmits microwaves on the surface of a target object, and scattering lights of various angles are generated; the microwave scattering transmitter receives the scattering lights of the target object, and the obtained scattering lights are finally transmitted to the net device; the net device is an important device of microwave radio frequency circuit measurement, microwave scattering curves can be obtained through the analysis of the net device, and the oil film thickness inversion is carried out through utilizing the microwave scattering curves and a scattering electromagnetic model; and the whole device can be convenient and flexible to operate through mounting a movable window and a sliding-rail-type support on a ship. The microwave scatterometer can be applied to oil spilling detection on the sea all day and all weather, the ship borne microwave scatterometer is convenient and flexible to detect the oil spilling, and simultaneously the oil film inversion by the microwave scatterometer is relatively accurate.

Description

technical field [0001] The invention relates to a device for retrieving the thickness of an oil film, in particular to a device for retrieving the thickness of an oil film with a ship-borne microwave scatterometer, which is used for measuring the thickness of the oil film of an oil spill on the sea. Background technique [0002] At present, the methods and means commonly used to monitor marine oil spills are satellite spacecraft, remote sensing monitoring aircraft and ocean patrol ships, but the remote sensing data received directly from satellites and aircraft contain a large amount of information, and are affected by objective conditions such as weather Lots of jamming signals. [0003] Active microwave remote sensing is of great significance in offshore oil pollution monitoring, because it not only has the advantages of all-day and all-weather observation, but more importantly, microwave remote sensing can be used to quantitatively invert oil film thickness. In order to ...
