Abstract

Studi ini berfokus pada evaluasi spesifikasi minimal perangkat SDR (Software Defined Radio) untuk modul pemancar pada berbagai aplikasi radar CC-OFDM MIMO. Teknologi radar ini menawarkan keunggulan seperti ortogonalitas multidimensi, peningkatan resolusi jarak dan azimuth, fleksibilitas konfigurasi, serta kemampuan menghasilkan beberapa sorot ortogonal secara simultan. Namun, kompleksitas desainnya memerlukan kajian mendalam terhadap keterbatasan perangkat keras, termasuk kebutuhan DSP block, bandwidth, memori, serta faktor DAC (Digital-to-Analog Converter) dalam implementasi praktis. Pendekatan penelitian mencakup analisis sistem radar, pemecahan komponennya, serta pengembangan model matematis untuk memetakan hubungan antara parameter masukan (jumlah beam, subcarrier, simbol, bandwidth) dengan indikator performa utama (resolusi jarak, waktu pada target, dan kemampuan deteksi). Simulasi menggunakan MATLAB dilakukan untuk mengukur kebutuhan operasi dan RFLOPS pada berbagai konfigurasi aplikasi radar. Hasil simulasi menunjukkan bahwa radar pengawasan dengan 63 beam, 2048 subcarrier, dan 12 simbol membutuhkan 40.3 juta operasi, sementara radar otomotif dengan 60 beam, 128 subcarrier, dan 1 simbol hanya memerlukan 200 ribu operasi. Analisis spesifik terhadap FPGA melibatkan evaluasi kemampuan DSP block, latensi, pipeline, serta pengaruh DAC terhadap efisiensi konversi sinyal. Penelitian ini juga mencakup pengembangan formulasi kebutuhan perangkat keras berdasarkan batasan desain, seperti alokasi memori untuk kode Golay, distribusi subband, serta sinkronisasi faseuntuk mempertahankan ortogonalitas antar sinyal.Selain itu, penjadwalan transmisi dan penerimaan dirancang untuk mengurangi coupling antar elemen dan mendukung pengolahan sinyal paralel. Hasil penelitian memberikan panduan komprehensif dalam desain dan implementasi radar CC-OFDM MIMO, termasuk optimalisasi perangkat keras untuk aplikasi spesifik seperti radar pengawasan, otomotif, dan jangkauan pendek. Kontribusi penelitian ini meliputi formulasi hubungan parameter masukan dengan kinerja sistem, evaluasi spesifikasi minimal FPGA dan DAC, serta pengembangan panduan implementasi yang efisien untuk kebutuhan misi tertentu

This study focuses on the evaluation of the minimum specifications of SDR (Software Defined Radio) devices for transmitter modules in various CC-OFDM MIMO radar applications. This radar technology offers advantages such as multidimensional orthogonality, increased range and azimuth resolution, configuration flexibility, and the ability to generate multiple orthogonal beams simultaneously. However, the complexity of its design requires an in-depth study of hardware limitations, including the need for DSP blocks, bandwidth, memory, and DAC (Digital-to-Analog Converter) factors in practical implementations. The research approach includes radar system analysis, component breakdown, and mathematical model development to map the relationship between input parameters (number of beams, subcarriers, symbols, bandwidth) with key performance indicators (range resolution, time on target, and detection capability). Simulations using MATLAB are performed to measure the operational requirements and RFLOPS in various radar application configurations. Simulation results show that a surveillance radar with 63 beams, 2048 subcarriers, and 12 symbols requires 40.3 million operations, while an automotive radar with 60 beams, 128 subcarriers, and 1 symbol only requires 200 thousand operations. Specific analysis of the FPGA involves evaluating the capabilities of the DSP block, latency, pipeline, and the effect of the DAC on signal conversion efficiency. This research also includes the development of hardware requirement formulations based on design constraints, such as memory allocation for Golay code, subband distribution, and phase synchronization to maintain orthogonality between signals. In addition, transmission and reception scheduling are designed to reduce coupling between elements and support parallel signal processing. The results of this research provide comprehensive guidance in the design and implementation of CC-OFDM MIMO radars, including hardware optimization for specific applications such as surveillance, automotive, and short-range radars. The contributions of this research include the formulation of the relationship between input parameters and system performance, evaluation of minimum specifications for FPGA and DAC, and development of efficient implementation guidelines for specific mission requirements
