“…The portable system setup and easy experimental preparation make it possible to acquire SAR images with multiple incident angles and multiple orbits more flexibly [10]. It is convenient for various applications such as local terrain mapping or target scattering measurement [11]. MiniSAR can also perform data fusion with spaceborne SAR and manned airborne SAR to form a multi-height, multidimensional and multi-level remote sensing system.…”

This paper extends the segmental aperture imaging (SAI) algorithm [28] which tackles the challenges of synthetic aperture radar (SAR) imaging of miniaturized synthetic aperture radar (MiniSAR) onboard multi-rotor unmanned aerial vehicle (UAV). The SAI algorithm is developed based on an accurate phase error model of both translational and rotational motion of UAV. It does require auxiliary positioning data such as GPS/INS. We further extend it to simultaneously estimate and reconstruct the 3D trajectory of UAV from parameters derived from SAI motion compensation. Thus, it in fact accomplishes the simultaneously location and imaging (SLAI) using UAV-borne radar. It is first validated and evaluated via raw signal simulation using realistic trajectory data. For experiment purpose, a multirotor-borne MiniSAR system FUSAR-Ku is developed. Experimental results show that the proposed algorithm can achieve decimeter-resolution imaging performance as measured by various metrics, while simultaneously accomplishing centimeter-to-decimeter 3D self-positioning capability. It is a first demonstration of SLAI mode with a multirotor-borne MiniSAR.

“…Radar is a common tool used in many applications such as imaging for earth monitoring application, missile guidance in military application, and remote sensing for environmental and weather forecast applications [1,2]. Synthetic Aperture Radar (SAR) is an active sensor that has its own source of illumination and can operate during day or nighttime, illuminate with variable look angle and cover wide area [3].…”

This paper proposes a technique for synthesizing multiple point target scatterer Synthetic Aperture Radar (SAR) echoesin real-time. Traditional approaches require high computation resources to calculate the complex SAR echoes due to its complex mathematical model. The proposed technique employs the low computation Direct Digital Synthesis (DDS) approach to generate these complex sinusoid echoes. The proposed Synthetic Aperture Radar Echoes Synthesizer(SAR-ES)is capable of synthesizing SAR echoes accurately in real-time and was built in a Field Programmable Gate Array (FPGA) platform. The system can be used as a testbed to validate and evaluate the performance of a real-time SAR processing algorithms/system prior to the actual flight mission. This could help in reducing the frequency of flight trials and to reduce the SAR system development risk especially for satellite-borne SAR system.
