A direction-finding mothed based on power measurement in space

摘要

Nowadays, a growing number of satellites have been sent to the space, the electromagnetic environment is worse than any before. The electromagnetic wave disturbs the receiving module to receive the effective signal, even break the satellites down. So we have to detect where the disturb microwave came from. We can detect the continuous wave with lots of methods, just like the TDOA and the phase interferometer. But there is less way to measure the impulse wave, especially the wave which width of the impulse only has 10ns wave. It is hard to detect and measure it with the traditional method. This paper has realized the detecting with four antennas and created a new method to make sure the direction of both impulse and continuous wave.
