Abstract
There is provided a feeding network device for improved direction estimation. The feeding network device according to an embodiment of the disclosure includes a first coupler, a second coupler, a first delay, a second delay, a crossover, a third coupler, a fourth coupler, a third delay, and a fourth delay. Accordingly, one sum beam and a plurality of difference beams are emitted through the feeding network device of the array antenna, and improved direction estimation is possible through a plurality of monopulse ratios, and accordingly, improvement of direction estimation in a monopulse radar device is expected.
