Othr radars
WebThe first radars developed by the U.S. Army were the SCR-268 (at a frequency of 205 MHz) for controlling antiaircraft gunfire and the SCR-270 (at a frequency of 100 MHz) for detecting aircraft. Both of these radars were available at the start of World War II, as was the navy’s CXAM shipboard surveillance radar (at a frequency of 200 MHz). Webthe data obtained from the real OTHR. All detection data obtained from installed, operational OTHR radars is sent to the Command and Control (C2) servers, via the communication network, Figure 1. The collected detection data passes through the top layer in the signal processing hierarchy – the tracking application (Stojković et al, 2016).
