A clutter rejection scheme is proposed for synthetic aperture radar (SAR) imagery based on two-stage two-dimensional principal component analysis (two-stage 2DPCA) followed by a bipolar eigenspace separation transformation (BEST) and a multilayer per

Issue of automated target detection in ISAR can be stated as what features enhance objects of interest from the rest of the data. Much experimentation done in this area have used Fourier transforms for preprocessing the raw signal data. Generally the

High gain and low noise figure are desired features of any erbium doped fiber amplifier (EDFA) based configuration. However, in L band region, low power and quantum conversion efficiencies have restricted EDFA based systems. The paper presents simula

The variation of gain in erbium doped fiber amplifier (EDFA) based optical networks has a direct implication on optical signal to noise ratio (OSNR) and system capacity. In this paper, investigations have been carried out to analyze the gain and nois

In the letter, a high gain-naturally flattened L-band erbium-doped fiber amplifier (EDFA) is demonstrated. The system uses two bidirectionally pumped lasers for exciting Er3+ in three cascaded fiber amplifiers. The maximum gain of ∼36.4 dB and equa

This paper presents a segmentation based lossy image compression (SLIC) algorithm. The segmentation scheme (Biswas and Pal, Pattern Recog. Lett. 21 (2000)), entropy based and hierarchical in nature, provides sub-images of homogeneous regions. The com
