Remote sensing today plays an important role in ensuring sustainability and protection of natural resources, in saving time and energy in industry and agriculture, and in many other applications. These applications were previously reserved for large industries, however, with recent developments in electromagnetic millimetre-wave (mm-wave) technology it is possible to build multi-spectral and radar sensors with reasonable resources. Our aim is to develop and demonstrate a Synthetic Aperture Radar (SAR) platform based on 24 GHz FMCW (Frequency Modulated Continuous Wave) radar module. For SAR processing we will use a modified Range Migration algorithm implemented on an embedded computer platform along with all the control signalling and processing. Processed SAR images will be passed through a developed object detection algorithm which will allow the system to work as a standalone platform for autonomous detection of various objects or intrusions. The paper will present the details of the development process and the developed algorithms along with the obtained results.
