Study on High Frequency Resolution Profile Based on the LS-ESPRIT Algorithm

The radar seeker has the problem that angle resolving power is low and there is the angle twinkle. It makes the guide precision of the radar seeker is lower than the optical seeker. Therefore, the profile model technology is researched. The frequency domain profile is one of the profile model technology. If this technology is used, the frequency resolving power of the millimeter wave radar seeker must be improved. The FFT algorithm can not get higher frequency resolving power, so the LS-ESPRIT algorithm is proposed in this paper. This algorithm improves frequency estimation precision and resolving power. The result of the emulation proves that this algorithm is effective.
