An algorithm for radiometric and geometric correction of digital SLAR data

In The Netherlands an accurate SLAR system with digital data recording is used for measurements within the framework of the national microwave remote sensing research program. However, the images are disturbed by unwanted platform motions due to, e.g., turbulence at the low operating height (300–3000 m) of the SLAR system. An algorithm is...

Critical Dynamics: The Expansion of the Master Equation Including a Critical Point

In this thesis it is shown how to solve the master equation for a Markov process including a critical pointby means of successive approximations in terms of a small parameter.A critical point occurs if, by adjusting an externally controlled quantity, the system shows a transition from normal monostableto bistablebehaviour. Examples of the...

The weather forecast under the weather

The weather forecast as broadcast several times a day, appears to be too long for effective storage in human memory. Out of 12 to 32 items per message a maximum of seven ( plus or minus 2) were reproduced. Selective listening to parts of the message reduced the number of correctly recalled items to about five. Addition of a long-term weather...

Recent onmiddellijk geheugenonderzoek bij zwakzinnigen [Investigation of short term memory in mentally retarded subjects]

The aim of this literature review is to get a preliminary answer to the problem of the type of information processing deficit of undifferentiated retardates (with an IQ of about 70). Taking the topic of verbal short-term memory as a framework, it appears that children or adults of a subnormal intellectual level can store new information as long...

Measured performance of a sequential two-step detection scheme

Measurements have been carried out to compare a sequential two-pulse detection scheme with conventional single-pulse detection. Measured and computed results are in good agreement.

Niet-conventionele luchtopnametechnieken

Tot nu toe heeft waarneming van de aardkorst voornamelijk plaats gevonden met behulp van fotografische middelen vanuit een vliegtuig en alleen in dat deel van het elektromagnetisch spectrum, dat het zichtbare licht en het fotografisch infrarood omvat. Het laatste decennium echter zijn systemen tot ontwikkeling gekomen, die ook waarneming...

Luchtwaarneming met niet-conventionele systemen; III. Integratie en automatisering der verschillende waarnemingssystemen

Integration and automation of the various scanning syslems. Non-conventional mapping systems, such as the side looking radar and the thermal infrared scanning systems give an electrical signal as output which is converted into an image. This conversion can cause losses in the information obtained in the air. It seems profitable therefore to use...

Correlator technology

The paper reviews a number of designs of cross-correlation receivers for the detection of active underwater transmissions. Particular attention is given to the various structures of phase insensitive receivers, and to the problems concerned with clipping of the input signal and the reference function.
