Morphological dilation for radar image enhancement

The use of radar technology as a defense equipment in the maritime territory has been widely applied in almost all regions of Indonesia. FMCW radar displays the raw data streamed from the DSP device. It is often observed that the data plotting results formed in an incomplete echo image because of the non-continuous pixels between the pixel data with the surrounding. This is caused by the execution time of the plotting process could not accommodate the changes of subsequent data. There are two ways to overcome these problems, by upgrading hardware capabilities, and perform image processing that stored in the buffer before it is displayed on the screen. This paper describes the design of morphological dilation which is applied in the plan position indicator (PPI) radar to improve the quality of radar image so that it can improve the quality of the extraction object in the research that has been done to reduce the loss of the object when the object tracking process takes place.
