Apart of the linear Kalman filter, SkyRadar also presents an implementation of the interacting multiple model (iMM) filter for object tracking.

One of the most powerful statistical estimation techniques, which is widely applied in navigation, radar tracking, satellite orbit determination, autonomous driving, and many other fields is the Kalman filter. This digital filter provides a quite accurate estimation of the next state (position, movement, temperature, etc.) from any possible noisy input signal, in real time, which makes it very suitable for radar navigation and tracking purposes.

The following video shows the algorithms Moving Target Indication (MTI) , MTI with post processing, Moving Target Detection (MTD) as well as MTD with Doppler filter, applied on raw data of a 24 GHz FMCW.

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.
