# [Signal Cleaning and Target Tracking in FreeScopes – A Walk-Through](https://www.skyradar.com/blog/signal-cleaning-and-target-tracking-in-freescopes-a-walk-through)

Understanding radar signal processing is crucial for ATSEP qualification, military radar operations, and academic training in surveillance technologies. To support this, we’ve created a practical walk-through video showcasing FreeScopes' capabilities in live signal analysis and cleaning.

In this session, we use pre-recorded IQ data—captured from SkyRadar's NextGen training radar—and walk through the signal processing pipeline in [FreeScopes](https://www.skyradar.com/products/digital-signal-processing). The step-by-step demonstration includes:

- [**Source Suppression**](https://www.skyradar.com/en/8ghz-radar-training-system/freescopes-basic-i-description) to eliminate persistent clutter,
- [**Static Threshold Filtering**](https://www.skyradar.com/en/8ghz-radar-training-system/freescopes-basic-i-description) for initial noise reduction,
- **[Moving Target Detection](https://www.skyradar.com/blog/topic/mti-mtd) (MTD)** to extract moving objects,
- [**Kalman Filtering**](https://www.skyradar.com/blog/topic/kalman-filter) to refine tracking,
- Visualization through **A-Scopes** and **PPI Scopes**.

This example illustrates just a small part of our broader training ecosystem, which combines real-time radar data, simulators, and recorded datasets—designed for hands-on training and advanced radar education.
