The Phased Array type-L band Synthetic Aperture Radar -2 (PALSAR-2) is an active microwave sensor using L-band frequency and which produces various products of different resolutions and performance. PALSAR-2 is flown on board the Japanese earth observation Advanced Land Observing Satellite 2 (ALOS -2) and was developed by the Japanese Aerospace Exploration Agency (JAXA). PALSAR-2 data can be acquired during day or night, increasing the temporal coverage of data for a particular spatial extent. PALSAR-2 is capable of detailed, all-weather, day and night observations and repeat-pass interferometry.
