Frequency Diverse Array (FDA) is a brand-new electronically scanned radar system. The time-range-angle three- dimensional correlation characteristics of its beampattern have broad application prospects in the fields of electronic counter- measures and security communications. One-dimensional uniform linear FDA array (ULFDA) has the problem of angle-range coupling in the transmit beampattern. To solve this problem, this paper adopts sine based on the symmetrical subarray density taper array structure. The frequency offset obtains the dot-shaped beampattern pointing control method at the target point posi- tion. In addition, we analyze the time-varying problem of the FDA pattern, and get the conclusion that the mainlobe of the density tapered array sin-FDA based on the subarray structure has a fixed direction in the angle dimension and changes in the range dimension.
