ELECTRONIC SCAN RADER DEVICE AND RECEIVING ARRAY ANTENNA
摘要
<p>Array antenna elements are divided into arbitrary L groups constituting a set. The greatest common divisor of a set constituted of the greatest common divisors of the element intervals of the groups is determined as an intergroup interelement greatest common divisor. Then, the number of array antenna elements L constituting a group is changed. The intergroup interelement greatest common divisor of all the L elements less than the maximum number of incoming waves is determined. The arrangement intervals of the array antenna elements are determined as values which do not produce L+1 or more linearly dependent directions of the incoming waves corresponding to the intergroup interelement greatest common divisor in the radar scan region according to the intergroup interelement greatest common divisor of the number of constituent groups L.</p>
