A Joint Technology of UAV SAR Based on OFDM Waveform

This paper presented a method based on compressed sensing that can be used for a joint technology of unpiloted aerial vehicles (UAV) radar detection and with the orthogonal frequency division multiplexing (OFDM) signal. OFDM is promising waveform in the next-generation future radar, it also brings the possibility of radar detection and wireless communication time-sharing processing under compatibility mode. An imaging method was performed by synthetic aperture radar imaging (SAR) with OFDM signals on the UAVs platform in this paper. Due to burden on data storage and transmission, an effective imaging algorithm is proposed to achieve high resolution with less collection data by UAV SAR based on compressive sensing focusing method. At the same time. The experimental data and simulation testified the proposed method.
