This paper focuses on the optimization of the image quality in the two ScanSAR modes of the forecoming ASAR sensor. The best trade-off between Noise Equivalent σ0 (NEσ0) and Equivalent Number of Looks (ENL) is achieved by optimizing a set of system and processing parameters. The optimization exploits a suitable end-to-end system model. This includes a closed form expression to compute ENL in a general case. Recommendations for processing and mosaicking are provided

Abstract

This paper focuses on the optimization of the image quality in the two ScanSAR modes of the forecoming ASAR sensor. The best trade-off between Noise Equivalent σ0 (NEσ0) and Equivalent Number of Looks (ENL) is achieved by optimizing a set of system and processing parameters. The optimization exploits a suitable end-to-end system model. This includes a closed form expression to compute ENL in a general case. Recommendations for processing and mosaicking are provided
