Instances of morbidity amongst rock lobsters (Panulirus cygnus) arriving at factories in Western Australia (WA) have been attributed to stress during post-harvest handling. This study used discriminant analysis to determine whether physiological corr

Polyphenoloxidase (PPO) activity in western rock lobster (WRL) hemolymph results in blackening, or melanosis, of the tissues after processing. The impact of processing temperatures on WRL PPO activity was evaluated under steady state and non-steady s

An approach to two-dimensional (2D) phase unwrapping for synthetic aperture radar (SAR) interferometry is presented, based on separate steps of coarse phase and fine phase estimation. A technique called adaptive multiresolution is introduced for loca

This paper explains the underestimation of phase slope and the consequent distortion of the phase surface, observed in two-dimensional (2-D) phase unwrapping by linear estimators, like least squares methods applied to synthetic aperture radar (SAR) i

Plasma cortisol in wild kahawai (Arripis trutta), an active pelagic marine fish, immediately after capture by hook and line was 8 ± 5 ng/ml (capture time, 4.9 ± 0.8 min, range 1–11 min). Capture by angling was accompanied by high levels of lactat

This paper presents signal properties of spaceborne, strip-map SAR for very large squint angles. Doppler centroid, azimuth bandwidth, and exposure time are derived in terms of the platform attitude and elevation angle. This allows a description of th

Coherent Change Detection (CCD) is the title given to a process used to detect differences between pairs of Synthetic Aperture Radar (SAR) images. In this process, the estimated coherence between a pair of complex SAR images is calculated and used to

The chirp scaling (CS) SAR processing algorithm uses the linear FM property of the transmitted pulses to provide accurate range cell migration correction. However, when the transmitted pulse is not linear FM, or if the FM rate is not known exactly, p

Image formation from squint mode synthetic aperture radar (SAR) is limited by image degradations caused by neglecting the range-variant filtering required by secondary range compression (SRC). Introduced here is a nonlinear FM chirp scaling, an exten
