Embodiment Construction
[0058] Such as figure 1 As shown, a coherent MIMO radar target detection method based on an iterative adaptive algorithm of the present invention obtains its position parameters by optimizing the reflection coefficients of the moving target and the static target respectively, specifically:
[0059] A When the observation target is a static target, the Doppler effect is not considered
[0060] A1. Determine the relationship model between the first echo signal observed at the nth observation point and the transmitted signal, the reflection coefficient of the target and noise interference as follows:
[0061] Y H ( n ) = Σ r = 1 P Σ a = 1 K α r , ...
