Abstract The area navigation system, discussed in this paper, is composed of ground
responders and a navigation terminal and can position a high-velocity aircraft and measure
its velocity. This navigation system is silent at ordinary times. It sends out a request signal
when positioning is required for an aircraft, and then the ground responders send a signal
for resolving the aircraft. Combining the direct sequence spread spectrum and frequency
hopping, the concealed communication mode is used in the whole communication process,
with short communication pulses as much as possible, so the system has strong
concealment and More >
