4 Methods for Measuring Pulse Modulations in Radar Signals Friday, January 20, 2023
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 …

3 Radiation Hazards (RADHAZ) and How to Mitigate Risk Wednesday, September 8, 2021
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 …

Monitoring the wireless spectrum for interference
3 System Design Challenges with Spectrum Monitoring Tuesday, September 7, 2021
The wireless spectrum is a finite commodity that is tightly regulated, managed and shared by all nations, manufacturers and citizens, who risk being fined if they are caught operating outside of what's regulated or licensed. The presence of interference or other signals of interest creeping into one's band of wireless spectrum is a daily occurrence to some and is of great concern to many who may …

Real-time Digital Signal Processing for Electronic Warfare Systems Monday, August 2, 2021
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 …

3 Ways to Generate Radar Signals with Arbitrary Waveform Generators Friday, October 30, 2020
Radar signals’ qualities make them inherently difficult to recreate with a signal generator. Their combination of carrier frequency, modulation bandwidth, and in most cases, their pulsed nature creates a series of requirements difficult to match with existing instrumentation. The increasing complexity of radar systems, the growing use of complex modulation techniques such as Barker codes, poly …

Recreating Real-World Chaos with Arbitrary Waveform Generators Friday, October 16, 2020
When testing complex electronic warfare and wireless communications systems, engineers and researchers need the flexibility to accurately recreate real-world signals. Unfortunately, the real world is messy, and its RF landscape can change rapidly from moment to moment. Thus, engineers often need to cycle through fast-changing signals quickly. With this need in mind, we’ve introduced new Streaming …

8 Challenges with Wideband Radar Thursday, August 27, 2020
Increasingly, designers of radar and electronic warfare (EW) systems and components need to perform modulation and pulse analyses at wider bandwidths. Spectrum managers also need to record and analyze hours of wide bandwidth data. There area number of test and measurement challenges associated with these needs, however.    Here are eight challenges with wideband radar: Generating …
