Abstract: Many research works using deep learning techniques for automatic vessel (or ship) detection from SAR images has good detection accuracy. But the main problem in these methods is false detection, primarily due to speckle presence. Therefore, we propose a novel pre-processing and deep learning model for vessel detection to address this problem. First, generate a three-channelled image (SarNeDe image) from a greyscale SAR image. Then, this image is used to train the model to predict the vessel's position in the SAR image. We studied the performance of different models using the SarNeDe technique and designed a lightweight model with the highest detection accuracy. We experimented on the public SAR ship detection dataset (SSDD) and dataset of ship detection for deep learning under complex backgrounds (SDCD) to validate the proposed method's feasibility. The experimental results indicated that our proposed method's vessel detection accuracy has increased with a reduced false detection percentage.
