N2 - The linear velocity of an arbitrary moving target comprises two orthogonal components with reference to the observing radar, namely radial and transversal velocities. The transversal velocity can be measured by an interferometric radar directly. When measuring multiple targets, there exist cross-terms that have no physical meanings and interfere with the extraction of the useful frequency. In this paper, we propose a new method utilizing a uniform linear receiving array with three antennas based on spatial interferometric averaging to suppress the cross-terms and measure the transversal velocity of multiple targets simultaneously. The basic idea of spatial interferometric averaging is to use subarrays of a uniform linear array to obtain an averaged correlation output, the phase terms of which contain the pure transversal velocity. Simulation results are provided to validate the effectiveness of the proposed method.
