Abstract:

In order to enhance the spectrum resolution of the coherent narrow-band radar which uses time sharing systems to track multiple targets, a method of connecting sparse sub-band measurements is presented. The method adopts a MUSIC algorithm to estimate the model parameter of the narrow-band radar echo, and connects sparse sub-band measurements based on the model. The spectrum resolution is enhanced by applying this method, which is advantageous to the extraction of the feature of the modulation spectrum. The effectiveness of the proposed method is verified by the experiment.
