In the world of embedded RF design, engineers are facing a shift in expectations. No longer is it sufficient to capture signals from a single point of view or rely on isolated snapshots of the RF spectrum. Modern systems are increasingly complex, integrating multiple radios, antennas, and subsystems, often operating simultaneously in tightly packed environments. These complexities demand solutions …
RF signals are more dynamic and unpredictable than ever, which presents new challenges for engineers. Even traditional vector spectrum analyzers struggle to capture transient or intermittent signals, leaving you without a complete picture of how your circuit or system is performing.
Tektronix SignalVu-PC spectrum analyzer software now provides three advanced triggers enabling you to visualize …
Modern technologies such as MIMO require the need for wide bandwidth, phase coherent, multi-channel analysis. Antenna elements in a MIMO radar system operate independently to cover a wide, often 180-degree, field of view without the need for directivity adjustments. This significantly improves scan times. The MIMO radar employs time, frequency, or coding techniques in each transmit signal to …
Radar applications today, whether found in defense or in aerospace, increasingly require analysis across multiple channels. For AESA antenna, transmitter and receiver module calibration both synchronization and wide bandwidth capture is important and being able to synchronize multiple channels for efficient calibration can be challenging.
Radar DSP and system integrator engineers working in FPGA …
Engineers and researchers whose work involves MIMO, phased array, and beam forming need a signal analysis tool that offers wide bandwidth and multi-channel capability. Oscilloscopes would seem to be a good choice – except many are either not designed to analyze RF signals or are limited to analyzing a single RF channel at a time.
But RF spectral and modulation analysis of multiple channels …
Modern radar signals make use of intra-pulse modulation or modulation on pulse (MOP), such as a linear frequency modulation (LFM), or some form of phase modulation (such as a bi-phase Barker code) to improve range resolution. They also include modulation on pulse to occupy more bandwidth and thus decrease the probability of intercept (POI). Additionally, intra-pulse modulation can include some …
If you are involved in military, aerospace or defense and have been around radar and communication systems, with high-power RF transmitters and high-gain antennas, you are probably aware of the many risks associated with Radio Frequency Radiation (RFR) Hazards. RF emissions from these systems have the potential to cause catastrophic damage to operations and maintenance personnel, ordnance and …
Evaluating and characterizing wideband communications, radar and electronic warfare systems in real time is challenging. Lacking a commercial off-the-shelf (COTS) alternative, some radar test teams stream test data to an inherently non-deterministic computing device such as a PC or laptop, inevitably leading to lost or missing data with no ability to verify that data is being recorded as expected …
In a few short years, the number of drones, or unmanned aerial vehicles (UAVs), purchased has soared. In the US alone, the FAA projects the small model hobbyist UAV fleet will more than double from an estimated 1.1 million vehicles in 2017 to 2.4 million units by 2022. Worldwide, Teal Group’s World Civil UAS Market Profile and Forecast projected in 2018 that non-military UAS production (Commercial …
