A Robust SAR NLFM Waveform Selection Based on the Total Quality Assessment Techniques

Design, simulation and optimal selection of cosine-linear frequency modulation waveform (CNLFM) based on correlated ambiguity function (AF) method for the purpose of Synthetic Aperture Radar (SAR) is done in this article. The selected optimum CNLFM waveform in contribution with other waveforms are applied directly into a SAR image formation algorithm (IFA) and their quality effects performance ...

The Object Detection Efficiency in Synthetic Aperture Radar Systems

The main purpose of this paper is to develop the method of characteristic functions for calculating the detection characteristics in the case of the object surrounded by rough surfaces. This method is to be implemented in synthetic aperture radar (SAR) systems using optimal resolution algorithms. By applying the specified technique, the expressions have been obtained for the false alarm and cor...

Application of Displacement Map Produced by Interferometric Synthetic Aperture Radar Technique in Height Datum Determination in the Subsidence Area

Damages due to subsidence such as destruction of watering system and agricultural fertile soil, wells increasing, damage to the roads, bridges and high ways and disordering in the water and gas supplying usually are irreparable and costly. As a huge amount bench marks of height network of Iran are placed in the subsidence area, changing their heights is a challenge for NCC. In this study, a new...

Speckle Reduction in Synthetic Aperture Radar Images in Wavelet Domain Exploiting Intra-scale and Inter-scale Dependencies

Synthetic Aperture Radar (SAR) images are inherently affected by a multiplicative noise-like phenomenon called speckle, which is indeed the nature of all coherent systems. Speckle decreases the performance of almost all the information extraction methods such as classification, segmentation, and change detection, therefore speckle must be suppressed. Despeckling can be applied by the multilooki...
