“…Moreover, "positive attitude" created the high level in intention to adopt drone delivery services, which is in line with the findings of Yoo et al (2018). The results about the relationship between drone convenience and customers' attitude are similar to the study of Sun et al (2021). However, drone convenience does not generate higher costs.…”

“…In the case of self-service technology, convenience is expressed through three main aspects: geography, time (such as opening times) and effort (such as ease of use) (Duarte et al, 2018). Speed concern is defined as a service attribute that is incorporated into the design of drone services to improve customers' control over personal or financial information when using the service (Sun et al, 2021). Compatibility is defined as the uniformity and accuracy of drone services.…”

Since e-commerce in the world is becoming increasingly popular, it leads to an increase in demand for a more efficient delivery system. Drone delivery innovation, with its distinct attributes, is contributing several advantages for delivery services. This paper studies the impact of drone delivery services on customers’ intention in Vietnam. The research uses correlation analysis and structural equation modeling (SEM) to analyze the data of 405 valid observations collected in a structured questionnaire survey in Vietnam. The paper reveals that convenience, speed, and compatibility affect customers’ attitude while convenience and compatibility have no negative effects on costs. Convenience has the highest impact on customers’ attitude, while speed concern has the lowest impact. In regard to customers’ intention to use drone delivery services, attitude has a strongly positive impact, while costs have a negative influence.

“…Yet, the proposed solution is limited to bistatic systems with a stationary ground transmitter and a moving receiver, making it inapplicable for active monostatic systems, where both transmitter and receiver are mounted on the same moving platform. The authors in [27], [28] investigated the use of a geosynchronous SAR system, where the AoI was illuminated by a satellite and echoes were collected by a passive sensing UAV. For instance, in [27], a multi-objective optimization problem for minimization of the distance traveled by the UAV-SAR was formulated and solved.…”

In this paper, we investigate joint 3-dimensional (3D) trajectory planning and resource allocation for rotary-wing unmanned aerial vehicle (UAV) synthetic aperture radar (SAR) sensing. To support emerging real-time SAR applications and enable live mission control, we incorporate real-time communication with a ground station (GS). The UAV's main mission is the mapping of large areas of interest (AoIs) using an onboard SAR system and transferring the unprocessed raw radar data to the ground in real time. We propose a robust trajectory and resource allocation design that takes into account random UAV trajectory deviations. To this end, we model the UAV trajectory deviations and study their effect on the radar coverage. Then, we formulate a robust non-convex mixed-integer non-linear program (MINLP) such that the UAV 3D trajectory and resources are jointly optimized for maximization of the radar ground coverage. A low-complexity sub-optimal solution for the formulated problem is presented. Furthermore, to assess the performance of the sub-optimal algorithm, we derive an upper bound on the optimal solution based on monotonic optimization theory. Simulation results show that the proposed sub-optimal algorithm achieves close-to-optimal performance and not only outperforms several benchmark schemes but is also robust with respect to UAV trajectory deviations.

“…SAR has unique advantages over optical sensors in terms of all-day and all-weather imaging capabilities, which is widely used in military and civil fields. Current research on SAR includes bistatic SAR imaging [1,2], spaceborne SAR [3][4][5], and moving target recognition [6][7][8], to name a few.…”

This paper introduces a fast backprojection synthetic aperture radar (SAR) imaging algorithm based on wavenumber-domain spectral splicing. The traditional fast backprojection (FBP) algorithm establishes the polar coordinate system with the center of the sub-aperture as the origin. Therefore, the coordinates of the image obtained from each sub-aperture are different. Sub-aperture images must be projected to a uniform coordinate system before they can be coherently superimposed to form the final image, which requires a large amount of calculation. In order to deal with this problem, this paper proposes a novel imaging method, which uses the same polar coordinate system for each sub-aperture. The sub-aperture images are then spliced in the wavenumber-domain, and directly added after upsampling. This method avoids the projection from each sub-aperture to the uniform coordinate system, thus improving the imaging accuracy and efficiency. At the same time, the algorithm is suitable for various configurations, and can achieve good imaging results for bistatic forward-looking SAR and high-speed mobile platform. Finally, simulations are presented to demonstrate the effectiveness of the algorithm.
