Improving efficiency of radar observations of navigation situation in ice radars under strong interference

نویسندگان

چکیده

The article considers the specific features of radar observations surrounding navigation situation in ice radars (IR) polar latitudes and reasons their possible decreasing effectiveness. There is described a negative effect radio waves received by IR due to reflection from hydrometeorological formations that occupy large area scanned space. ways improving operation creating necessary conditions are analyzed. It has been inferred case observing small-sized objects against background strong extended interference, digital processing data slightly improves functioning locators. found out order improve detecting small targets measuring parameters, it ensure safety overload caused interference at stage primary information (before using filter). structure device proposed, which allows not only partial weakening operation, but also suppressing this interference. stated locator noise immunity during its achieved additional blocks composition quickly detect short-term pulses processed signal convert them into form almost completely compensate for continuous method mathematical modeling used study effectiveness proposed signal-to-noise ratio it, reaction time, signals after processing. According analysis results experiment there have made conclusions about lack factors limiting possibility as part optimal variant implementation.

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Antenna Deployment Method for MIMO Radar under the Situation of Multiple Interference Regions

In this paper, considering multiple interference regions simultaneously, an optimal antenna deployment problem for distributed Multi-Input Multi-Output (MIMO) radar is investigated. The optimal antenna deployment problem is solved by proposing an antenna deployment method based on MultiObjective Particle Swarm Optimization (MOPSO). Firstly, we construct a multi-objective optimization problem fo...

Multifrequency Polarimetric Synthetic Aperture Radar Observations of Sea Ice

The first known fully polarimetric airborne synthetic aperture radar (SAR) data set of sea ice is introduced. Images were acquired in the Beaufort, Bering and Chukchi seas in March 1988, during a campaign for validation of Defense Meteorological Satellite Program Special Sensor Microwave Imager radiometer ice products. Statistics of the magnitude, phase and polarization of complex backscattered...

Satellite Microwave Radar Observations of Climate-related Sea-ice Anomalies

Since 1991 a number of international satellites have collected microwave radar image data over Arctic and Antarctic sea ice. The recent successful launch of the ADEOS I satellite, with the NASA NSCAT instrument, also enables additional weather-independent global sea-ice radar data to be acquired and archived in the US. With its pair of 500 km-wide parallel swathes, this radar scatterometer is c...
