GENERATOR OF VIDEO SIGNAL FOR SIMULATING RADAR INTERFERENCE PHENOMENON

摘要

the generator produces a radar image in the form of spirals, consisting of dotted lines with random position on the screen, with the possibility of selecting next parameters: number of spirals.the thickness, the interruption, the intensity.the video signal which stimueala phenomenon d einterferenta radar is produced by generating two voltages in the form of the teeth of the saw.a synchronized trigger signal range and one autooscilant, followed by their comparison and starting a monostabil when the two signals become equal.the signal obtained is passed through a gate, open periodically by a signal which ensure interruption spiral, and then through a video signal amplifier.
