Algorithm and new structure for radar sliding MTD

Moving target detection (MTD) is a high-performance signal processing approach for pulse Doppler radar. High-performance radar calls for sliding MTD (SMTD). Traditional SMTD processing massively increases computational load, resulting in difficulty of implementation. A modified moving DFT algorithm and a new SMTD structure are proposed in this paper. The new SMTD structure adopts both batch-mode signal channel estimation and the modified moving DFT algorithm, which leads to a dramatic reduction of the computational load. The new SMTD structure can be regarded as an adaptive filter for other applications as well
