Deign and Development of RADAR for Quadcopter
Project Area of Specialization Artificial IntelligenceProject SummaryCivil aviation regulatory authorities demand all the aspects of safety of unmanned air vehicles to accommodate them in national airspace along with manned aircrafts. For BLOS UAVs to be integrated into National Air Space one of the primary requirements is that it can “Sense and Avoid” surrounding Air Traffic, be it manned or unmanned. For this UAV should be completely autonomous and by removing the pilot from the system necessitates replacement of his functionality with regard to detecting and avoiding threats. In order to increase the existing airspace for UAV and the expansion of UAV technology in commercial market the active area of current research and approaches are sense and avoid functionality of UAV
For a UAV to avoid collision the fundamental tasks are “sense and avoid”. The project will be mainly focusing on the sensing (detection)of the target by the UAV. Project aims to simulate a complete airborne radar including propagation channel and RF front end and to develop a functional prototype radar for UAV which will form the SENSE (detection) part of sense and avoid capability essential for integration of UAVs in National Air Space and execute autonomous collision avoidance. The goal will be achieved by designing and development of airborne RADAR that will be installed on quad copter. The functional prototype of the RADAR will be able to determine the distance, quadrant and the speed of the target of enhanced RCS within the range of 500 meters to 1km.
The project is divided into four major parts. The simulated complete end to end radar model including radar propagation channel and RF front end, Radar Signal Processor based on embedded system, prototype of airborne radar, carry out its integration on UAV and conduct flight testing. Signal processing will be performed “off-line”.
Project Objectives- Understanding radar functionality at subsystem level.
- Carry out mathematical calculations of radar system design with available resources
- Simulate an airborne radar propagation channel and RF front end.
- Using the simulated data a radar signal processor based on a microcontroller will be implemented
- A functional prototype of airborne radar to detect a large target, UAV relative speed and quardrant of target
- Modify the model for airborne usage
- Install the prototype on UAV and carryout functional check on UAV.

- Unmanned aerial vehicles (UAVs) are attractive options in many fields for numerous reasons, including their inherent cooperativeness, flexibility, and small support needs.
- These characteristics make the UAV popular for both civil. and military applications
- In the field of Avionics it is an active area of current research. So, Pakistan will come instep with presently ongoing research in Sense and Avoid Avionics
