Envelope and square-law channels fusion

For pulse Doppler radars, two signal processing ways are typical: a peak power envelope demodulation and a square-law demodulation. Statistical detection processing follows in each of them. It is worth to exploit any available signal characteristic, especially in heavily fluctuated target or environment, or low SNR. The data fusion system may say my piece. This paper focuses to fuzzy signal fusion applied on two-channel demodulation and CFAR detection techniques.
