Height Measurement With Meter Wave MIMO Radar Based on Precise Signal Model Under Complex Terrain

Meter wave radar height measurement is one of the most difficult problems in meter system. At present, popular methods include beam splitting method, MUSIC algorithm and maximum likelihood estimation which can achieve good performance under flat ground. However, real ground not ideal condition, situation undulating also very complicated. Under this above dropped sharply. Many researchers solve problem by improving robustness algorithm. authors think that key to establish a refined signal model. In paper, accurate model reflection coefficient, point condition are established provide for measurement. Then we deduce application generalized MIMO terrain fact, method proposed paper matching target measurement, traditional be regarded as mismatch. The simulation results show accuracy precise much better than simplified
