Beta-thalassaemia is an autosomal recessive disorder and it is a public health problem in the Malaysian Malays and Chinese. This disorder mainly results from point mutations, small insertion or deletions in the β-globin gene complex. Beta-thalassaemia major patients require life-long monthly blood transfusions and iron-chelation therapies to sustain their lives. Mutation characterisation is necessary...
An upgrade programme to add a bistatic collection capability to the Ingara airborne X-band fully-polarimetric imaging radar has recently been completed, and the first field trials of the new bistatic SAR system were conducted in December 2007. This involved a set of experimental SAR data collections in a bistatic geometry, in which the airborne radar was operated in a fine-resolution (600 MHz bandwidth)...
Fine resolution spotlight synthetic aperture radar (SAR) imagery collected on a circular flight path is used to investigate the variation in ship detection performance with respect to three fundamental radar parameters: the transmit/receive polarisation combination, the incidence angle and the azimuth angle. The polarisation combinations examined are HH, HV, VV, RR and cross-slant 45deg. Three different...
The accuracy with which distributed-target polarimetric calibration algorithms estimate crosstalk and the ratio of Tx-to-Rx channel imbalance is compared. The algorithms investigated are minor variants of previously-published algorithms but rederived for notational and definitional consistency. Numerical simulations were used to assess the algorithms' performance in the absence of noise. Results indicate...
