Its transmission technology is primarily based on solid-state amplifiers. Due to their low output power (200 W), pulse compression techniques are necessary to achieve adequate sensitivity without decreasing range resolution. The initially employed phase-coding technique prevented the amplifier from operating at maximum efficiency, achieving only 4% of the available duty cycle. To overcome this limitation, a pulse compression technique based on chirp waveforms is developed and evaluated, enabling more efficient use of the transmitted power and achieving a duty cycle of 12%. The results demonstrate an increase in the average signal-to-noise ratio (SNR) of 13.87 dB, a reduction of the blind range by 151 m, and an increase in the unambiguous Doppler velocity to ±20 m/s. Consequently, these improvements in the duty cycle will strengthen the detection capabilities of the high-resolution SOPHy radar system and make a significant contribution to the observation and study of atmospheric phenomena in Peru. con los siguientes autores: David Evangelista¹, Juan Carlos Espinoza¹, Danny Scipión¹ y Ricardo Reinoso-Rondinel²³ (presentador) ¹ Instituto Geofísico del Perú, Lima, Perú ² Civil Engineering, Hydraulics & Geotechnics, KU Leuven, Leuven, Belgium ³ Royal Meteorological Institute of Belgium, Brussels, Belgium PARA MAS DATOS COMUNICARSE CON DAVID EVANGELISTA. 4.
