Signal processing of interferometric inverse synthetic aperture radar (InISAR) with long orthogonal baselines for air target three-dimensional (3-D) localization is introduced. The echo signals are recorded by an InISAR system which operates at Ka band and has two 10m-long baselines. The signal processing includes imaging, interferometric processing and 3-D localization. A method called dual-frequency conjugated processing (DFCP) is employed to solve phase ambiguity within the beam width, then a rough angle estimation is completed. With the rough estimation result, an exact angle estimation is conducted. Simulation results demonstrate the efficiency of the proposed signal processing method.
