Abstract
Distributed radar is a radar with multiple small aperture antennas scattered, which can greatly improve the physical aperture of radar antenna array. Large aperture antenna can realize high precision angle measurement. This paper studies the high precision angle measurement technology of distributed radar in different working scenarios, so as to deal with multiple measurement scenarios and detect multiple types of targets. When the SNR of target echo is very low, transmitting all coherent signal to realize focusing in space, and using full array antenna to improve the SNR of echo signal. When the SNR is enough, the distributed radar antenna can be coherent clustered, then achieve the measurement, and further improve the accuracy of angle measurement. Distributed radar can achieve maximum precision of angle measurement under different scenarios, which can give full play to its advantage and enhance its usefulness.
