Description
Technical field
The present invention relates to the marine pollution monitoring technology, relate in particular to a kind of offshore spilled oil and suspension remote sense monitoring system and monitoring method thereof.
Background technology
Offshore spilled oil and the suspension meeting coastal marine site of severe contamination, the ecologic equilibrium of destruction water environment, make animals and plants circle be subject to great danger, and to coastal economy, activity causes significant impact, from causing the great attention of national governments.For this reason, need to take necessary measure to be monitored and control offshore spilled oil and suspension.
Remote sensing technology is the effective means of offshore spilled oil and suspension monitoring.Conventional monitoring method has fluorescence excitation, ultraviolet, optics, infrared and microwave remote sensing.For example, but there is limitation separately in these remote sensings, and, optics and infrared remote sensing are limited to weather condition, can not round-the-clock, round-the-clockly carry out work; And the wavelength of microwave remote sensing is longer, penetrability is strong, can round-the-clock, round-the-clockly carry out work, but its spatial and temporal resolution also can't meet practical application request, and the sensor cost is higher.
Emerging GLONASS (Global Navigation Satellite System) reflected signal GNSS-R(Global Navigation Satellite System-Reflection) remote sensing technology is to utilize the reflected signal of Navsat to carry out remote sensing to atural object.With ocean, land face microwave remote sensing means such as existing scatterometer, radar altimeter, synthetic-aperture radar, compare, Navsat group GNSS can provide the signal of L-band endlessly, and do not need to develop special transmitter, the receiver of GNSS-R is a plurality of satellite-signals in field of view of receiver simultaneously, belonging to two station/multistation radar modes aspect remote sensing mechanism, this mode of operation can improve spatial and temporal resolution greatly; Simultaneously, owing to being operated in the L-band that penetrability is stronger, so can monitor all-time anf all-weather.In addition, the GNSS-R receiver belongs to passive reception, itself does not need to transmit, so volume and weight is all very little, needed power consumption is also little, therefore, has convenient, characteristics flexibly in atural object monitoring.The GNSS Navsat will provide accurate, free detectable signal for the mankind in coming few decades, and this detectable signal has long-term stability, therefore, this technology for monitoring atural object, analyze feature changes rule etc. ideal means be provided.
