  1. The invention of radio waves

  2. The advent of commercial aviation

  3. The threat of war in Europe in the late 1930s

  4. The need for traffic management systems

The correct answer is: The threat of war in Europe in the late 1930s

The significant factor that spurred serious research and development of RADAR was the threat of war in Europe in the late 1930s. As tensions escalated leading up to World War II, nations recognized the urgent need for advanced technologies that could enhance national security and military operations. This environment of impending conflict created a strong impetus for innovation in detection and surveillance technologies, leading to the rapid advancement of RADAR systems. During this period, the primary goal was to develop the ability to detect incoming enemy aircraft and ships, which prompted governments to invest in scientific research and collaborate with engineers to create effective RADAR systems. This is why the late 1930s was a pivotal moment in the advancement of RADAR technology, as nations sought to equip their militaries with superior detection capabilities to maintain an advantage in warfare.
