Abstract:
ABSTRAKRadar pasif adalah salah satu jenis sistem radar bistatic dimana transmitter dan receiver berada di tempat berbeda. Sistem radar pasif dapat memaanfaatkan frekuensi siaran televisi yang tersedia sebagai sumber transmitter. Pada penelitian ini, radar pasif dibuat dengan Sofware Defined Radio (SDR) sebagai sistem komunikasi yang dapat mengkofigurasi penerima televisi digital sdr-dongle RTL2832U yang dimodifikasi dan perangkat lunak GNU Radio. Hasil pengujian delay pada gelombang 1,2,3 untuk objek manusia adalah 0,192, 0,36 dan 0,53 detik, untuk objek sepeda adalah 0,332, 0,5 dan 0,67, untuk objek motor adalah 0,422, 0,69 dan 0,86 detik, untuk objek mobil adalah 0,538, 0,7 dan 0,87 detik sehingga dapat disimpulkan bahwa sistem radar pasif yang dirancang dapat mendeteksi benda bergerak dimana pegerakan target menyebabkan pergeseran puncak Cross-Correlation.Kata kunci: Radar Pasif, Cross-Correlation, SDR, Frekuensi Televisi, RTL2832U ABSTRACTPassive radar is a type of bistatic radar system where the transmitter and receiver are in different places. Passive radar systems can utilize the available television broadcast frequencies as transmitter sources. In this study, passive radar is made with Software Defined Radio (SDR) as a communication system that can configure a modified RTL2832U sdr-dongle digital television receiver and GNU Radio software. The delay test results on waves 1,2,3 for human objects are 0.192, 0.36 and 0.53 seconds, for bicycle objects are 0.332, 0.5 and 0.67, for motor objects are 0.422, 0.69 and 0.86 seconds, for car objects are 0.538, 0.7 and 0.87 seconds so it can be concluded that the passive radar system is designed to detect moving objects where moving targets causes a shift in the peak of Cross-Correlation.Keywords: Passive Radar, Cross-Correlation, SDR, Television Frequency, RTL2832U

Abstract:
This paper shows the vulnerabilities present in a wireless sensor network implemented over a long-range wide area network (LoRaWAN) LoRaWAN, and identifies possible attacks that could be made to the network using sniffing and/or replay. Attacks on the network were performed by implementing a protocol analyzer (Sniffer) to capture packets. The Sniffer was implemented using the RTL2832U hardware and visualized in Wireshark, through GNU-Radio. Tests showed that data availability and confidentiality could be threatened through replay attacks with LoRa server verification using HackRF One and GNU-Radio hardware. Although the LoRaWAN specification has, frame counters to avoid replay attacks, under given the right conditions, this measure could be violated even deny service to the node on the server.

Abstract:
In this paper, we design and make a prototype of an aerial spectrum monitoring system that consists of a ground control station and a four-rotor unmanned aerial vehicle (UAV). This UAV carries a software-defined radio (SDR) receiver to perform spectrum monitoring tasks, including signal strength, frequency occupancy, and signal analysis. A light and low-cost SDR-based dongle consisting of RTL2832U chip and R820T tuner is employed as the monitoring receiver. A global positioning system and an electronic compass system are built on board to report the UAV’s position and direction. The open-source development platform GNU Radio is employed to design the radio monitoring system through the use of software-defined blocks. The proposed aerial monitoring system can detect radio signals in the frequency range of 25–1700 MHz that in practice covers the FM and DVB bands. With the prototype monitoring system, we have performed a few measurement tasks, including signal strength, waterfall display, and demodulation for identifying FM stations. Our proposed aerial monitoring system is more cost-effective than land-vehicle monitoring stations because of its much more flexible implementation.

Abstract:
El objetivo fue realizar el estudio y análisis de la calidad de servicio en la transmisión am digital mediante el uso de códecs en USRP. La Metodología de desarrollo muestra claramente cómo se realizó el prototipo para la transmisión y recepción, empezando con la selección de dispositivos, el diseño, la ejecución y el análisis de los resultados obtenidos. Se basa en el estudio de las condiciones particulares en la transmisión y recepción de señal en AM digital (DRM), la implementación del transmisor en GNU Radio, la configuración del receptor en HDSDR y Dream SDR. Además de las tarjetas Ettus USRP N210, Ettus USRP B200 y RTL-SDR REALTEK RTL2832U. El resultado de este estudio fue la calidad de los niveles de servicio evaluados en la velocidad de transmisión (Kbps) y la relación señal / ruido (SNR) para determinar la fidelidad en la recepción de señales digitales. En base a los resultados se define que las características de funcionamiento de cada modo de robustez para un determinado canal de transmisión varían los valores de la velocidad de transmisión y la relación señal a ruido, ofreciendo el modo B una mejor protección de la señal con respecto al ruido, mientras que el modo A ofrece mayor velocidad de transmisión. El sistema DRM emplea las mejores tecnologías de compresión de sonido ya que usa los algoritmos de audio y voz del MPEG-4 que brinda excelente calidad de sonido a bajas tasas de bit como la codificación AAC.
