Prototype L-band Bistatic Radar Using Software-Defined Radio

This paper describes the design and implementation of a bistatic radar prototype using SDR and 2 GHz frequency panel patch antennas. The development of this prototype arises as an alternative design of new speed traffic radar systems controlled using software-defined radios that work in L-band frequency, the research focuses on making a prototype of radar that can be installed in rural areas where the speed control of cars is scarce, causing in many cases tragedies and accidents due to speeding. To experiment with bistatic radar, algorithms were programmed in Labview based on the transmit and receive power levels of the radar antennas. The power levels captured by the receiver are stored as data, which helps define the behavior of the target's distance from the power; using addition formulas, using correlations and linear regression, the equation with which the distance and speed of the radar target are calculated is obtained.
