• ### Analysis and application of differential propagation phase shift in polarization-diversity radar measurements of precipitation at centimeter wavelengths

Publication Year: 1990, Page(s):3/1 - 3/4
| | PDF (244 KB)

Discusses the relation between differential propagation phase shift ΔΦ and rainrate R, which is found to be nearly linear and be almost insensitive to the dropsize distribution parameters. The studies show that by using ΔΦ method, we can extract rainrates from CDR radar and correct propagation effects on CDR radar data. It is clear that the technique of differential propagation...

• ### The detection of unusual events in remote sensed imagery

Publication Year: 1990, Page(s):2/1 - 2/4
| | PDF (248 KB)

Describes a novel technique for the detection of unusual events in remote sensed imagery when the images contain a high level of background clutter. The technique combines conventional image processing algorithms with statistical methods to derive simple models of image backgrounds. These fractal-based models have been shown experimentally to give a good fit to statistics derived from remote sense... View full abstract»

• ### Polarimetric image processing: an important new tool for remote sensing

Publication Year: 1990, Page(s):7/1 - 7/9
| | PDF (380 KB)

Whenever electromagnetic radiation is reflected from a surface, it becomes polarised to a degree, dependent upon surface structure, texture and angle of incidence. If the polarisation information from the reflected radiation is extracted from conventional intensity information by an imaging polarimeter it is possible to reveal detail about the surface that cannot be obtained by any other imaging t...

• ### The detection of atypical image features

Publication Year: 1990, Page(s):4/1 - 4/4
Cited by:  Papers (1)
| | PDF (196 KB)

A set of adaptive transforms is defined which emphasises atypical features in an image. The transforms emphasise features such as regions of atypical grey level, boundaries, or unusual multispectral properties. The result of the transforms is a new image in which the difference between an atypical feature and the rest of the image has been enhanced View full abstract»

Publication Year: 1990
| | PDF (992 KB)

The following topics were dealt with: MuSIP, multisensor image processor; detection of unusual events in remote sensed imagery; radar measurements of precipitation; atypical image features; subsea image interpretation; design of advanced coded pulse radar waveforms; and polarimetric image processing View full abstract»

• ### Subsea image interpretation-a problem in remote sensing

Publication Year: 1990, Page(s):5/1 - 5/4
| | PDF (308 KB)

Although remote sensing is generally associated with satellite imagery, it can also be applied to sea-floor imagery collected by acoustic surveying techniques. Sea-floor surveying is important in environmental and oceanographic research, and for mineral prospecting and marine civil engineering projects. The main instrument for sea-floor mapping is the side-scan sonar. This generates an image of th... View full abstract»

• ### MuSIP-multisensor image processor (a system for the automated fusion and analysis of multisource images)

Publication Year: 1990, Page(s):1/1 - 1/4
| | PDF (252 KB)

As the volume of data collected by an increasing number of satellites escalates, it has become of paramount importance that methods of coping with and making best use of this information are developed. Current trends are moving towards automatic and knowledge-based analysis systems particularly for monitoring applications where the same kinds of interpretation task must be repeated many times. The... View full abstract»

• ### A design procedure for the design of advanced coded pulse radar waveforms generated from a finite set of samples

Publication Year: 1990, Page(s):6/1 - 6/7
Cited by:  Papers (1)
| | PDF (344 KB)

The optimal design of waveforms generated from a finite set of samples is a commercially significant problem of growing importance for the following two reasons. First, on account of progress in the fields of memory and digital-to-analogue convertor technology it is now feasible to generate waveforms with suitable durations and bandwidths for radar applications from a finite set of digital samples...
