WYPSAR: Wide-swath yields by partial signal of synthetic aperture radar

A novel and promising type of Synthetic Aperture Radar (SAR) concept for High Resolution and Wide Swath (HRWS) observation is presented. Different from conventional SAR systems, the proposed WYPSAR transmits a long pulse of Linear Frequency Modulation (LFM), but receives only partial signals of echoes, however, the focused image of the short received signals can be nearly the same length as the transmit pulse. And the rest time of the pulse interval can be used to receive echoes from other swaths. By WYPSAR, the HRWS observation is carried out much simpler than using the technology of multi-channel systems. After an introduction to the new concept, a simple example is presented. At last, the signal processing technique is discussed and a simulation result follows.
