Abstract

A novel pair of interleaved OFDM (I-OFDM) signals is proposed to overcome the limitations of existing signals for simultaneous polarimetric measurement. The proposed I-OFDM signal pair exploits the orthogonality features between different sub-carriers within a single OFDM chip, and can then yield the theoretical orthogonality. The isolation limitation defined by the BT product for linear frequency modulated (LFM) and phase-code modulated (PCM) signals thus can be overcome, the proposed waveform pair then significantly increases the efficiency for polarimetric measurements.
