Design of a Low-Cost and Configurable Radar for Border Security

Radars are usually very expensive and have a limited frequency range, limited instrumented range, fixed radar type (either pulsed or frequency modulated continuous wave), fixed waveform, and no target simulation. This article addresses all these limitations through the development of a low-cost configurable software defined radio (SDR) radar for border safeguarding. The radar was used to detect humans, cars, animals, and airborne targets but this article only addresses the simulation mode of the radar and the detection of cars. It can be stated here that the major novelty of this work is the presentation of the complete design flow of such an SDR-based radar.
