- W1969155369 abstract "The signal processors in pulse Doppler radar can detect the target signal which is spectrally separated from clutter, even if the signal is -60 dB weaker or more than main- lobe clutter, so in missile hardware-in-the-loop it is required that the noise resulted by clutter reconstruction architecture should be -60 dB lower than main-lobe clutter. Because of the restriction, a new method of clutter reconstruction with specific power spectrum is proposed, which include conversion from power spectrum to vector spectrum, randomization of phase, inverse Fourier transform, and then windowing and overlapping the series time domain sequence, which guarantee the expectation value and variance of random sequence continuously. The simulation results demonstrate that by applying the method, the ratio of signal to noise is increased from 30 dB to 60 dB." @default.
