摘要

渐进式扫描地形观测(TOPS, Terrain Observation by Progressive Scans)模式允许在方位角分辨率和波束扫描的方位角场景覆盖范围之间达成妥协，而方位角分辨率、方位角场景覆盖范围、工作时间(获得完整波束扫描的时间)、最大扫描角度和PRF的选择是机载TOPS模式应用的系统问题。针对这一问题，本文提出了一种有助于确定上述参数的分析方法。该方法将该问题视为一个优化问题，即给定工作周期;搜索满足工作周期的最大扫描角度和方位角分辨率，搜索结果为数据对，可作为计算场景多普勒带宽和方位角覆盖的选项。

Performance analysis of airborne TOPS mode

TOPS (Terrain Observation by Progressive Scans) mode allows a compromise between azimuth resolution and azimuthal scene coverage by beam-scan and the selection of azimuth resolution, azimuthal scene coverage, working period (time during which a complete beam-scan is obtained), maximum scanning angle and PRF is a systematic problem for airborne TOPS mode application. Focusing on this issue, this paper proposes an analysis method that helps decide the aforementioned parameters. The proposed method treats the issue as an optimization problem, i.e., given working period; search the maximum scanning angle and azimuth resolution that satisfy the working period, the search results are data pairs that could be used as options to calculate the scene Doppler bandwidth and azimuthal coverage.
