Target classification by radar

IET Seminar on High Resolution Imaging and Target Classification, 2006
Target classification by radar has enormous potential with many important applications. So far, with a couple of notable exceptions, this has proved to be an extremely challenging problem with no obvious solution. The chief method for improving the quality of information gathered has been to improve resolution in both range and cross-range dimensions ...

Target Discrimination and Target Classification in Echolocating Bats

1988
Geometrical and textural properties of reflecting targets result in a specific filtering of the echolocation sounds used by the various bat species. They are therefore represented in the temporal and spectral structure of the echoes. These echo features can be used as cues for target recognition, classification and discrimination.

Target classification by conventional radar

Proceedings of International Radar Conference, 2002
An approach to aircraft target classification by conventional radar is presented that uses the engine modulation on radar echoes from the detected target. The echo series are rearranged into a graph and the modulation signatures are extracted by an optical Fourier transform.

Certification/Classification Targets for Beef

Proceedings of the British Society of Animal Production (1972), 1987
Successive UK Governments have supported the market for finished cattle by various subsidy schemes. One of these depended on making up the difference between the average market price and a predetermined guaranteed price on an individual animal basis when market prices fell below the guaranteed price.

Adaptive underwater target classification system

SPIE Proceedings, 1999
This paper presents a new adaptive underwater target classification system for in situ robust classification ins presence of environmental and target signature changes. A wavelet packet-based feature extraction scheme is used as a front-end processor to extract pertinent features in each subband.

Broadband classification of submerged targets

ICASSP '77. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
A recently proposed echo analysis scheme, based on a polynomial model of the target transfer function and an optimally Doppler tolerant transmitted waveform is applied to relatively low frequency broadband echoes from a number of simple submerged targets.

Cooperative Control for Target Classification

2005
An overview is presented of ongoing work in cooperative control for unmanned air vehicles, specifically wide area search munitions, which perform search, target classification, attack, and damage assessment. The focus of this paper is the cooperative use of multiple vehicles to maximize the probability of correct target classification.

Classification crédale multi-cibles - Multi-target evidential classification

2012
In this paper, we study the problem of joint tracking and classification of several targets. Targets are considered to be known and sufficiently separated so that they cannot be confused. Our goal is to shed light on the contribution of credal classification over the Bayesian classification.

Target Classification and Hypothesis Testing

1977
A simple target classification problem, illustrative of all target classification problems, is presented and its solution given. The problems created for classification by unknown target properties and their alleviation are discussed. Finally an extension of the ideas to dynamic situations is outlined.
