| Abstract | ||
| The two dimensional spatial MTI technique discussed before [1, 2] has the advantages of detecting moving targets which have zero Doppler shift and also improve the probability of detecting target immersed in heavy or fluctuating clutter. In this paper the application of the spatial MTI is extended to the three-dimensional radar. In this case, the pixel represents a volume element with an elevation coordinate in addition to the range and azimuth. The size of the required memory increase because each memory cell in the two dimensional case is replaced by an array, the length of which depends on the number of cells in the elevation coordinate. The effect of different radar parameters, namely the pulse repetition frequency, pulse width, the antenna beam-width,..., on the performance of the spatial MTI technique is included. Application of the spatial Mil on the airport landing radar was discussed. The effect of the limited searching sector and the nearly radial target motion is considered. The considered case study shows the feasibility of using the new technique to improve the landing radar performance without affecting the resolution. | ||
