Abstract:
A novel range-spread target detection algorithm in white Gaussian clutter for missile-borne radars is presented. For missile-borne radars, range migration of the target echoes during a coherent processing interval (CPI) is serious, which disperses the echo energy of the target and increases the difficulty of target detection. In this paper, range alignment for target echoes is accomplished in the frequency domain during the process of digital pulse compression. Then a range-spread detection algorithm based on the waveform entropy (WE) of the average combination of high range resolution profiles (HRRP) is addressed, which has the property of constant false-alarm rate (CFAR). Finally, the detection performance is assessed by Monte-Carlo simulation, and the results indicate that the detection performance of the proposed detector is superior to the traditional energy integrator and is robust for different HRRPs of the target.
