SkyRadar's FreeScopes platform offers a range of distinctive advantages and unique characteristics that make it an ideal choice for educational institutions and training programs focused on radar technology and signal processing.

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 following video explains in detail the 2 Dimensional CFAR.

This video show several blocks in the digital signal processing chain that allow to enhance the visibility and tracking of moving targets. We show CFAR, Moving Targete Detection with Doppler Filtering, a Heatmap and the I and Q signals.

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.

The following video visualizes the Doppler frequencies of a person approaching and moving away from the radar source. We apply Fast Fourier Transform.

This article features a video on an FFT plot. It has been implemented in real-time, just by connecting and calibrating the blocks in the block-diagram. The video shows well how the FFT amplitude moves to the right, when the person approaches and to the left when the person moves away from the source.

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.

FreeScopes Basic II is the advanced module in SkyRadar's modular radar analytics and visualization environment. It includes important two-dimensional functions like 2D-Fast Fourier Transform (FFT), 2D-CFAR. It also includes additional functions like the spectogram, several windows functions and a 3D Scope. This article introduces into the module.
