Unbiased Range-Preserving Estimators

1994
An estimator is said to be range-preserving if its values are confined to the range of what it is to estimate. The property of being range-preserving Is an essential property of an estimator, a sine qua non. Other properties, such as unbiasedness, may be desirable in some situations, but an unbiased estimator that Is not range-preserving should be ...

Estimation Of Range-doppler Radar Images

1993 IEEE International Symposium on Circuits and Systems, 2002
It is shown that most accurate reconstruction of a range-Doppler target density that can be computed from N waveforms and their echoes is obtained by transmitting the singular functions corresponding to the N largest singular values of two kernels derived from the target density.

Optimum Realizable Continuous Range Estimation

IEEE Transactions on Aerospace and Electronic Systems, 1968
The ability to detect the presence or absence of a target is no longer the fundamental design criterion when the vehicle to be tracked is cooperative. In spacecraft tracking or navigation systems, for example, emphasis is placed on post-acquisition performance. Therefore, classical radar theory and design techniques are not specifically applicable.

Range estimation via multidimensional segmentation

Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004
A new graph-theoretic algorithm for stereo range estimation, utilizing a Mumford-Shah variational, multidimensional segmentation of a 3D or 4D spatio-(temporal)-parallax space to implicitly solve the stereo correspondence problem, is described. Initial results and comparison with an area correlation range estimation algorithm demonstrate that it is ...

Numerical ranges and stability estimates

Applied Numerical Mathematics, 1993
Numerical ranges or fields of values of matrices are not only an important topic in matrix theory but also in applications, such as stability estimates of some discretization schemes of ordinary differential equations, which is mentioned by the author, and stability analysis of linear control systems.

Nephelometer estimates of visual range

Atmospheric Environment (1967), 1979
Abstract A survey of basic contrast brightness theory and integrating nephelometer operational theory shows the inherent difficulty of trying to derive the true meteorological visual range Vm from nephelometer measurements of scattering visibility Vs. The effects of background horizon sky spectral radiance, atmospheric spectral scattering coefficient
