The Spectrogram looks at the received power from the targets. It represents the first one-dimensional Fourier transform and is given in a logarithmic scale. The received power spectrum allows to detect moving targets.

In this video, we give an introduction into I and Q Signals in the context of digital signal processing. We handle and visualize them in FreeScopes Basic I.

We walked in front of a rotating radar. Look at the impressive images and the toolset for education in ATSEP, vocational qualification and university education.

When it comes to radar, the FFT (Fast-Fourier Transform) is used to convert time domain signals into frequencies. An example of its use is for converting the dual channels of a pulse-Doppler radar from time domain into range-Doppler data.

With FreeScopes 7, SkyRadar's 24 GHz FMCW training radar can be applied as simply as the NextGen Pulse radars. The students can concurrently and independently apply the Fast Fourier Transform in their browsers and switch between frequency and time domain, just as needed.

Everyone knows what an antenna is when they see one and many people generally understand its purpose. But beyond that the science of wireless communication is often left to IT specialists and engineers. It helps to tell yourself circular graphs aren't really that overwhelming. Here are the basics for a more technical understanding of antenna beams and how they work.

When does an ATM radar actually see an aircraft, and when does it only see one target (instead of a formation of warplanes). Why does a radar sometimes miss an aircraft. Here some explanation.

Cyber threats continue to grow exponentially around the globe. By 2022, Cisco estimates that 1 trillion networked sensors will be embedded in devices globally, and that number is expected to swell to 45 trillion within 20 years. It is no wonder that there is a grave concern as these threats are no longer limited to targeting computers, corporate networks, or smartphones.

Windowing (also known as weighting) functions are used to combat spectral leakage from digital signal processing. This article explains how they are applied in radar technology.
