RADAR TECHNOLOGY FOR 2020 Despite the widespread availability of advanced passive sensors, which do not emit electromagnetic signals detectable by the enemy, radar remains the main sensor of modern combat aircraft. Modern radar systems offer significant performance and their associated technologies are constantly evolving. There are still some persistent unsatisfactory features, however, frequently stemming from trade-offs between design and cost, which are the objects of continuous investigation by designers, including: Some radars emit identical signals; Some transmit on only one frequency at a time; Some see only a limited area at any one time; and Many are still subject … Continue reading Radar Technology for 2020
