Mathematical algorithms for determination of mixed layer height from laser radar signals
نویسنده
چکیده
This paper describes different mathematical algorithms used in the determination of mixed layer height (MLH) from the laser radar (lidar) signals. These methods are successfully applied to the indigenously developed portable lidar signals for retrieval of the depth of pollutants mixing in the lower atmosphere. The study also includes intercomparison between the methods. KeywordsPortable lidar, Laser radar, lidar signal, ABL height, Analytical methods

Adaptation of Rejection Algorithms for a Radar Clutter
In this paper, the algorithms for adaptive rejection of a radar clutter are synthesized for the case of a priori unknown spectral-correlation characteristics at wobbulation of a repetition period of the radar signal. The synthesis of algorithms for the non-recursive adaptive rejection filter (ARF) of a given order is reduced to determination of the vector of weighting coefficients, which realiz...
متن کاملDetection of some Tree Species from Terrestrial Laser Scanner Point Cloud Data Using Support-vector Machine and Nearest Neighborhood Algorithms
acquisition field reference data using conventional methods due to limited and time-consuming data from a single tree in recent years, to generate reference data for forest studies using terrestrial laser scanner data, aerial laser scanner data, radar and Optics has become commonplace, and complete, accurate 3D data from a single tree or reference trees can be recorded. The detection and identi...
متن کاملThree-stage inversion improvement for forest height estimation using dual-PolInSAR data
This paper addresses an algorithm for forest height estimation using single frequency single baseline dual polarization radar interferometry data. The proposed method is based on a physical two layer volume over ground model and is represented using polarimetric synthetic aperture radar interferometry (PolInSAR) technique. The presented algorithm provides the opportunity to take advantages of t...
متن کاملMeasurements of iron concentrate stockpile weight, from laser mapping to investigation of effective parameters on surface density
Determination of stockpile weight and stockpile inventory are critical to any quarry or mining operation, whether it is required by accounting firms or used internally for the quarterly balance of production and sales. Generally, errors and problems originate from two factors. Volume of stockpile that is traditionally worked out from the mapping results has a low accuracy due to irregular shape...
متن کاملApplication of Displacement Map Produced by Interferometric Synthetic Aperture Radar Technique in Height Datum Determination in the Subsidence Area
Damages due to subsidence such as destruction of watering system and agricultural fertile soil, wells increasing, damage to the roads, bridges and high ways and disordering in the water and gas supplying usually are irreparable and costly. As a huge amount bench marks of height network of Iran are placed in the subsidence area, changing their heights is a challenge for NCC. In this study, a new...
