In the present work, different remote sensing techniques have been used to analyze remote sensing data spectrally using ENVI software. The majority of algorithms used in the Spectral Processing can be organized as target detection and classification. In this paper method of target detection has been studied constrained energy minimization on the Therthar Lakeand surrounding area has been done.
Also the results that obtained from applying constrained energy minimization were more accurate than other method comparing with the real situation.
Keywords: Spectral Analysis, Target Detection, Constrained Energy Minimization, Minimum Noise Fraction.
