研究目的
To develop an end-to-end simulator for Geosynchronous SAR data to assess decorrelation effects and verify system performance during the design phase.
研究成果
The end-to-end simulator is effective for evaluating decorrelation impacts and system performance in GEOSAR design, providing insights into mitigation strategies and feasibility.
研究不足
The time-domain simulation can be computationally intensive, and the approach may require optimization for large scenes. Simplifying hypotheses are minimized but could still affect accuracy in some cases.
1：Experimental Design and Method Selection:
The simulator uses a time-domain approach for raw data simulation and a back-projection algorithm for processing. It models atmospheric and clutter decorrelation effects.
2：Sample Selection and Data Sources:
Utilizes system design parameters (e.g., PRF, SWST, SWL) and may use reflectivity images (e.g., from Sentinel-1) as input.
3：List of Experimental Equipment and Materials:
No specific physical equipment mentioned; it is a software-based simulator.
4：Experimental Procedures and Operational Workflow:
Involves pre-processing to generate sensor parameters, pulse-by-pulse simulation of echoes, and processing to generate L1 products with APS compensation.
5：Data Analysis Methods:
Performance assessment through comparison of simulated products (e.g., DEMO and SNCR images) before and after APS compensation.
