Extracting snowpack parameters from snow cover on sea ice or land is a time-consuming and potentially high-risk task. Moreover, deriving such parameters by manually digging a snow pit evidently yields low area coverage. We, therefore, propose a practical solution to this problem by mounting an ultrawideband radar system onto an unmanned aerial vehicle (UAV) to obtain information such as snowpack depth, density, and stratigraphy in order to increase personnel safety and extend coverage area. In this paper, we describe the development of radar system hardware and its mounting onto a UAV, as well as initial tests with this radar as a snow measuring device. Preliminary results from both ground and airborne testing show that the radar system is capable of obtaining snow depth information that corresponds well to in situ validation data with a correlation of 0.87. The radar system also works well while mounted on a UAV platform with little additional signal noise from vibrational and translatory movements.

“…Furthermore, in this era of technology, all the defense services should be equipped consequently. For instance, Wahab et al in [7] and Sreelakshmy in [8] designed antennas covering military radar and Ka-band. This kind of antenna in view of the mass production must be costeffective, light, and meet the requirements in terms of bandwidth, gain, impedance matching, and many other parameters.…”

Achieving antenna size reduction while maintaining high efficiency and multiband characteristics with wide bandwidths across all the operating frequency bands is highly demanded and challenging in microstrip antennas. A novel compact triband quasi‐rho‐shaped and cost‐effective antenna is designed on a 7 × 7 × 1 mm3 FR4 substrate having a permittivity of 4.4 and a loss tangent of 0.02. With an electrical size of 0.39λ0 × 0.39λ0 × 0.056λ0, where λ0 is the free space wavelength at 16.84 GHz, a circular slot and asymmetric microstrip feed are used to achieve the desires performance. The proposed antenna is designed, simulated, and optimized using high‐frequency structure simulator (HFSS) software, and its prototype is fabricated to validate its electromagnetic performance. Furthermore, an equivalent circuit is proposed using the Foster canonical model. The proposed antenna exhibits a maximum stable gain of 5.32 dB and an average radiation efficiency of 77.87% in all the operating frequency bands. The measurement results show that the antenna covers (16.84–18.15 GHz), (24.78–27.40 GHz), and (34.47–37.22 GHz) bands centred at 17.39 GHz, 25.98 GHz, and 35.83 GHz, respectively, with a minimum wide bandwidth (S11 ≤ −10 dB) of 1.31 GHz. The acquired results illustrate that the quasi‐rho‐shaped antenna is suitable for military radars and 5G applications.

“…Research on radar working at the SHF frequency has also been carried out to obtain high resolution, for example, coastal surveillance radar (CSR) [8]. The frequencies commonly used in radar systems are S band (2-4 GHz), C band (4-8 GHz), X band (8-12 GHz) and Ku band (12-18 GHz) [9] An antenna is one of the essential devices that will determine the performance of the radar system. if analogous to the human body, the antenna systems as an eye which is very vital [10] .…”

Radar tsunami merupakan salah satu alat deteksi yang digunakan pada system peringatan awal tsunami. Radar tsunami yang umum digunakan adalah radar High frekuensi yang memiliki jarak jangkauan jauh tetapi daya besar dan resolusi rendah. Untuk meningkatkan keandalan system peringatan tsunami dalam mendeteksi tanda-tanda tsunami dan monitoring dengan kecepatan update informasi yang tinggi, maka diperlukan system radar dengan resolusi yang tinggi. Resolusi yang tinggi dapat diperoleh jika radar memiliki bandwidth yang besar dalam spectrum radio. Peningkatan bandwidth dapat dilakukan dengan menaikan frekuensi kerja radar. Antena merupakan salah satu komponen penting yang dapat menentukan performa system radar. Oleh karena itu pada penelitian ini dirancangan antenna pada Super High Frequency untuk diaplikasikan pada system radar. Antena yang dirancang adalah antenna microstrip dengan patch rectangular. Spesifikasi yang diinginkan pada frekuensi 5,8 Ghz yaitu return loss≤-10 dB, VSWR≤2, bandwidth >150 Mhz, beamwidth>200. Setelah rancangan menggunakan simulasi memenuhi spesifikasi maka dilakukan pabrikasi dan pengukuran. Hasil pengukuran didapatkan pergeseran frekuensi menjadi 5,71 Ghz dengan return loss -21,346, VSWR 1,186, Bandwitdh 200 Mhz dan beamwidth 400 Oleh karena itu dapat dikatakan bahwa antenna yang dirancang dapat digunakan pada system radar tsunami
