    ABSTRACT: A novel pair of mutually-orthogonal radar waveforms is proposed for simultaneous polarimetric measurements (SPM). The proposed waveform pair exploits the orthogonality features between different subcarriers within a single orthogonal frequency division multiplexing (OFDM) chip, and is called interleaved OFDM (I-OFDM). With I-OFDM signals the isolation limitation defined by the bandwidth time (BT) product for frequently used waveform pairs like linear frequency modulated (LFM) and phase-code modulated (PCM) signals, can be overcome. The performance features of I-OFDM signals are theoretically analyzed; the application of I-OFDM signals and the corresponding signal processing scheme in SPM are presented. A significant increase of the polarimetric measurements efficiency by utilization of the proposed I-OFDM signals has been verified by experiments using an operational radar system.

    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.
