| Abstract(in English) | In MTI (moving target indicators) for a search radar, staggered PRF (pulse repetition frequency) is often used in order to narrow the region of blind frequency. A method for estimating the frequency of sinusoidal signals using AR model is effective for a few observable samples such as in the search radar. We have proposed the method for estimating the frequency of the staggered-sampled complex sinusoidal signals by calculating the roots of the higher-order polynomial based on the time-varying AR model. In this report, we propose the estimation method for the center frequency of unimodal clutter spectrum with multiple range bin by applying the above method. |
