Pulojekiti ya AERIS-10 yapanga njira yotseguka ya radar yomwe ingagwiritsidwe ntchito ngati nsanja yoyesera ndi ma antenna a phased array, pulse compression, Doppler signal processing, ndi target tracking. Ma schematics athunthu, mapangidwe a board circuit board osindikizidwa, ma bill of material (BOMs), mafayilo a Gerber opangira ma board, mapangidwe osindikizidwa a 3D, ndi mafotokozedwe a hardware block mu Verilog/VHDL amagawidwa pansi pa CERN-OHL-P (CERN Open Hardware Licence). Khodi ya firmware ya STM32 microcontroller, mautumiki othandizira mu C, ndi mawonekedwe azithunzi mu Python ali ndi zilolezo pansi pa layisensi ya MIT.
Mitundu iwiri ya radar ya phased-array yapangidwa: AERIS-10N (Nexus) ndi AERIS-10E (Extended). Mitundu yonseyi imagwira ntchito pa 10.5 GHz ndipo imagwiritsa ntchito pulsed linear frequency modulation (LFM). Kusiyana kuli mu mphamvu yotumizira (1W x 16 ndi 10W x 16), komanso kugwiritsa ntchito 8x16 planar antenna array ndi 32x16 array ya slot radiators mu dielectric-filled waveguide, zomwe zimapereka mtunda wa makilomita 3 ndi makilomita 20, motsatana.
Dongosololi ndi la modular, lokhala ndi ma board osiyana oyendetsera mphamvu, kupanga ma frequency, ndi ma RF units. XC7A100T FPGA imagwiritsidwa ntchito pokonza ma signal, pulse compression, kuwerengera liwiro la chinthu pogwiritsa ntchito Doppler Fast Fourier Transform, stationary object rejection (MTI), komanso kusunga constant false alarm rate (CFAR). Kugwira ntchito ndi kukonza zipangizo zozungulira kumayendetsedwa ndi STM32F746xx microcontroller.
Kukonza malo ndi malo enieni nthawi yeniyeni kumaperekedwa ndi GPS ndi masensa osayenda (accelerometer, gyroscope). Kuwongolera kwamagetsi kwa kuwala kwa scanning kumachitika mkati mwa ±45° kutalika ndi azimuth. Mota yoyendera stepper imapereka kuzungulira kwa antenna ya 360°. Kutsata zinthu zingapo nthawi imodzi n'kotheka. Chithunzi chojambulira chimayikidwa kuti chiwongolere radar, kutsatira zinthu zoyenda, komanso kufananiza ndi mapu.
Rada imapangidwa kuchokera ku zinthu zokhazikika zomwe zimapezeka m'masitolo. Mtengo wa ma chips ndi zinthu zoyambira pa rada yoyambira ndi pafupifupi $5000. Poyerekeza, ma rada amalonda a kalasi yomweyo amayamba pa $250.
