Baru-baru ini, menjadi penting untuk mengesan dengan pantas subjek manusia yang tertimbus di bawah rumah yang runtuh, runtuhan dan tanah akibat gempa bumi dan runtuhan salji untuk mengurangkan korban dalam bencana. Sistem pengesanan sedemikian telah pun dibangunkan sebagai satu jenis penderia anjakan gelombang mikro yang berdasarkan perbezaan fasa yang dihasilkan oleh gerakan payudara subjek. Oleh kerana hampir semua sistem terdiri daripada pasangan pemancar dan penerima tunggal, sukar untuk mengimbas kawasan yang luas dengan pantas. Dalam makalah ini, kami mencadangkan sistem radar multistatik frekuensi tunggal untuk mengesan subjek manusia yang bernafas yang wujud di kawasan yang dikelilingi oleh tatasusunan pemancar dan penerima. Sasaran bergetar boleh disetempatkan oleh algoritma MUSIC dengan amplitud kompleks dalam frekuensi Doppler. Algoritma ini disahkan oleh isyarat simulasi yang disintesis dengan penyelesaian ketat model sasaran sfera dielektrik. Kami menunjukkan hasil penyetempatan 3D percubaan menggunakan sistem radar Doppler multistatik yang dibangunkan sekitar 250 MHz.

Abstract: Recently, it has become important to rapidly detect human subjects buried under collapsed houses, rubble and soil due to earthquakes and avalanches to reduce the casualties in a disaster. Such detection systems have already been developed as one kind of microwave displacement sensors that are based on phase difference generated by the motion of the subject's breast. Because almost all the systems consist of single transmitter and receiver pair, it is difficult to rapidly scan a wide area. In this paper, we propose a single-frequency multistatic radar system to detect breathing human subjects which exist in the area surrounded by the transmitting and receiving array. The vibrating targets can be localized by the MUSIC algorithm with the complex amplitude in the Doppler frequency. This algorithm is validated by the simulated signals synthesized with a rigorous solution of a dielectric spherical target model. We show experimental 3D localization results using a developed multistatic Doppler radar system around 250 MHz.
