The Detection of Lengthened Objects by Pulse Altimeter
نویسندگان
چکیده
The algorithm of lengthened objects detection is based on statistical processing of reflected pulse altimeter signal. The method of maximum posteriori probability is applied to make a decision. Minimum of maximum posteriori probability is accorded with lengthened objects position. This fact is taken into account to detect the objects’ position. This algorithm allows autonomic navigation to be implemented. Two cases of the algorithm implementation are shown in this article. The first method is based on the unsharpened beam regime of radar altimeter and the second is based on the application of the Doppler’s filtration. The results of flight experiments proving the correctness of the created algorithm are introduced in this article.

Mars orbiter laser altimeter: receiver model and performance analysis.
The design, calibration, and performance of the Mars Orbiter Laser Altimeter (MOLA) receiver are described. The MOLA measurements include the range to the surface, which is determined by the laser-pulse time of flight; the height variability within the footprint determined by the laser echo pulse width; and the apparent surface reflectivity determined by the ratio of the echo to transmitted pul...
متن کاملEstimation and Analysis of Precipitable Water Vapor Using GPS Data and Satellite Altimeter
Determination of water vapor in the atmosphere plays an important role in forecasting weather conditions and precipitation studies. For this reason, it is very important to study the tropospheric delay, especially the wet component, which is due to the presence of water vapor in the atmosphere. In this paper, the amount of water vapor was estimated by altimeter satellite radiometer and GPS data...

We report results of a laser link experiment between a laser altimeter called light detection and ranging (LIDAR) aboard Hayabusa2 and ground-based satellite laser ranging stations conducted when the spacecraft was near the Earth before and after the gravity assist operation. Uplink laser pulses from a ground station were successfully detected at a distance of 6.6 million km, and the field of v...
متن کاملStatistical Background Modeling Based on Velocity and Orientation of Moving Objects
Background modeling is an important step in moving object detection and tracking. In this paper, we propose a new statistical approach in which, a sequence of frames are selected according to velocity and direction of some moving objects and then an initial background is modeled, based on the detection of gray pixel's value changes. To have used this sequence of frames, no estimator or distribu...
