A tracking algorithm employing HMA is proposed for more accurate guidance of autopilot system guided missiles and unmanned vehicles. HMA is based on spatial transform with triangular patches and 2-D affine transform, from which the information on rotation and scale changes is obtained. Also, we can adaptively adjust the size of the target block from these information. As a result, the algorithm provides more accurate tracking results than BMA when the object has rotational motion, zooming, or scale changes.

In this paper, radio propagation in subway tunnel was investigated using 1×2 microstrip array antenna at 2.4 [GHz] band. The results of narrowband channel measurements show that received power level for NLOS(non-line-of-sight) paths was decreased drastically as compared with LOS(line-of-sight) paths. In the results of wideband channel measurements using 10 shift registers in the sequence generator, mean access delay and RMS delay spread of Fan beam antenna was 3.5736 [ns] and 11.7327 [ns], respectively.
