摘要：
ISAR resolution evaluation is an important part of accuracy evaluation of space target imaging radar. Two difficult problems, i.e. the selection of evaluation criteria and the design of evaluation methods are discussed in detail. Then an ISAR cross-range scaling algorithm based on high precision orbit and telemetry attitude of space target is proposed. A new ISAR resolution evaluation method is established based on the new scaling technique. The method is validated by using the actual imaging test data for different types of space targets.
