The present project is based on research and design of a commercial generator of impulses that produces a high frequency monocycle pulse to detect nutrients in a farmland, before the development of the proposed design, it was necessary know concepts about of what are the GPR (Ground Penetrating Radar) in the transmitter module there is a signal generating stage and a modulator stage where the signal from the previous stage is adapted to obtain a final waveform that the GPR will emit. The joint work of these stages is what is called impulse generator. The design of basic function generators and their components was used as reference since the pulse generator of a GPR is electronically related to the laboratory equipment generating waveforms. Through comparative analysis, the suitable components for the pulse generator were selected, this is how the power levels with which the GPR of the trademark that exist in the market were investigated for the power supply.
In order to select the components that will produce the high frequency monocycle waveform, VCO’s (voltage controlled oscillators) and circuits with fast recovery diodes were chosen. Using the Advanced Design System (ADS) software from the company Agilent Technologies, the operation test was performed and it was observed that the selected devices generated the required pulse. Once the impulse generator was designed and obtaining correct results in the simulation, a cost analysis was made with respect to the total cost of the GPR, which presented the commercial viability of the proposed design. |
