And things work now, but I'm wondering what went so horribly wrong earlier and whether I can change that back, as I have a number of scripts that use the x.x.0.x setup that I'm a bit loathe to change. Long story short is that I had to reset the router to factory default and (currently) have everything set via the default, 192.168.1.1. NETGEAR GENIE ASSIGN STATIC IP PCI should add that I was not accessing the router via the app because I didn't want yet another damn app on my phone, but was using a wired connection to access the router through a desktop PC (Lubuntu 20.04LTS, if it matters). I had hoped to change the default IP of the router by simply editing its configuration to 192.168.0.1 but the moment I did this and "applied" the change and rebooted the router, I lost all contact. My new router, a Netgear Nighthawk R8000P, uses a default of 192.168.1.1, and a mask of 255.255.255.0 - which means that I'm only able to assign static IPs in the range of x.x.1.x. The SFR will be used to determine the practicality of detecting and classifying buried and concealed landmines and IEDs from safe stand-off distances.I have traditionally had a router at the IP 192.168.0.1 which is a) easy for me to remember and b) has allowed me to have static IPs for devices running in the x.x.0.x range (192.168.0.5, 192.168.0.100, etc.) The transmitter has the ability to produce approximately -2 dBm/MHz average power over the entire operating frequency range. The radar system is capable of illuminating range swaths that have maximum extents of 30 to 150 meters (programmable). The SFR has an operating frequency band which ranges from 300 - 2000 MHz, and a minimum frequency step-size of 1 MHz. NETGEAR GENIE ASSIGN STATIC IP FULLThe 4-channel system will be used to validate the SFR design which will eventually be augmented in to the full 16-channel system. While a preliminary SFR consisting of four (4) receive channels has been designed, this paper describes major improvements to the system, and an analysis of expected system performance. The SFR is designed to be a forward-looking ground- penetrating (FLGPR) Radar utilizing a uniform linear array of sixteen (16) Vivaldi notch receive antennas and two (2) Quad-ridge horn transmit antennas. The SFR utilizes a frequency synthesizer which can be configured to excise prohibited and interfering frequency bands and also implement frequency-hopping capabilities. Stepped-Frequency Radar (SFR) which allows for precise control over the radiated spectrum, while still maintaining an effective ultra-wide bandwidth. As part of ARL's Partnerships in Research Transition (PIRT) program, the above deficiency is addressed by the design of a. However, there is no control of the radiated spectrum in this system. The Army Research Laboratory (ARL) has developed an impulse-based vehicle-mounted forward-looking ultra- wideband (UWB) radar for imaging buried landmines and improvised explosive devices (IEDs). The information provided in this paper will be useful to the radar community in exploring developmental standoff detection solutions for military applications such as obscured target detection of obstacles and explosive hazards. An analysis of the gain, VSWR, beamwidth, and measured data from radar test of each antenna was performed, providing insights into each antenna’s performance on the SFR’s ability to detect buried targets. The antennas were also tested for their ability to detect buried targets in a simple stepped-frequency radar system using a network analyser as a transmitter and receiver. Gain, Voltage Standing Wave Ratio (VSWR), and antenna pattern measurements for each antenna are presented. This paper discusses a comparison analysis between a commercially available UWB antenna and the currently used TEM horns. The custom-made TEM horn antennas are used for the transmission of the SFR’s ultra-wideband. The SFR has an operating band of 300–2000 MHz, and a minimum frequency step-size of 1 MHz. We are currently developing a Stepped-Frequency Radar (SFR) which utilizes a custom-made uniform linear array of 16 Vivaldi notch receive antennas and two Transverse Electromagnetic (TEM) horn transmit antennas.
