Coverage Map of OTH-B coverage

Thanks to that unique design, OTH-B radar can detect aircraft thousands of kilometers away even if these aircraft fly at very low altitude. However, since OTH-B radar use very low frequency, they are not only highly inaccurate but also required antennas which are extremely large, the height of each individual antenna often as high as 15-20 meters while the whole radar array often between 2-3 km long. Furthermore, the receiving and transmitting array need to be separated and stationed around 150-200 km away from each other. Due to their extreme size, OTH radars are large and stationary targets [1][2]
