<p>PURPOSE:To obtain an antenna directivity data generating/delivering system which can deliver an antenna directivity data to each tracking station at a desired timing while responding easily and quickly to the modification of tracking station. CONSTITUTION:Source data D1-1,..., D1-n for calculating the antenna directivity data delivered from tracking stations are demodulated by demodulators 1-1,..., 1-n. Based on the demodulated data D2-1,..., D2-n, a main CPU 2 generates a predictive position/speed data S representative of the predictive values of position and speed of a flying object at a predetermined time later in a basic coordinate system. A branch unit 3 branches the data S and sub-CPUs 4-1,..., 4-n generate estimated antenna directivity data D3-1,..., D3-n representative of the directional angle of tracking antenna at each tracking station based on the branch predictive position/speed data S1-1,..., S1-n from the branch unit 3. Subsequently, modulators 5-1,..., 5-n transmit modulation data D4-1,..., D4-n to respective tracking stations at a same timing.</p> |
