%X To solve the direction-finding and communication of the micro aerial vehicle in peculiar environment, a new communication and tracking system is proposed. The main idea of this system is that the space-time OFDM signal carrying spatial information is transmitted. The transmitter adopts eight element antennas in this system, which are divided into four arrays to produce multi-beams. There are spatial information and communication message in the signal space of each OFDM subcarrier. The micro aerial vehicle with single antenna could determine the ambiguity resolution of multi-beams with many observed samples to estimate the precision direction of receiver relative to transmitter. This paper presents the geometry of antenna arrays, the space-time signal feeding antenna and the direction-finding algorithm of azimuth and elevation. The performances of bit error rate and direction-finding in the two-dimensional space through Gaussian channel are investigated.
