About Product

The Radar Training System is a real, safe-to-use pulse + FMCW radar platform designed for close-range object detection, SAR imaging, Doppler studies, and radar data classification. It supports multiple concurrent users and provides real-time radar signals for training, research, and machine-learning applications.

  • Real-time modular system with a facility for a minimum of 5 concurrent users to access the radar. (Expandable to 100 Users using a cloud server)

  • Teacher logs in to start the radar, and students can log in to conduct exercises independently in real time.

  • Allows users to manipulate live and pre-recorder IQ data from the Radar and work independently on the Modular Block diagram editor-based software with large libraries of Scopes, filters, and algorithms.

  • Allows students to play on the Radar Signal Conversion Chain by changing signal conversion functions like STC, DC Suppress, MTI, etc., at different stages concurrently and independently—web-based software with A-Scope, B-Scope, PPI, RCS estimation, CFAR, MTI, filters, window functions, and Doppler tools. Reads I/Q data and interfaces with MATLAB.

  • View multiple A-scopes, B-scopes, and PPI-scopes at various stages of the radar block diagram, enabling the comparison of the results and analysis of the results.

  • Modular for future upgrades by adding Modules like Air Traffic Control Modules to meet the requirements of ATCO (Air Traffic Controller) and ATSEP (Air Traffic Security Electronics Personal) curriculum.

Different targets/materials representing various radar cross‐sections (RCS) are supplied with the Radar Training System, including a corner reflector (retro‐reflector) consisting of three mutually perpendicular, intersecting flat surfaces and two spheres. The device is able to rotate to rotate the reflectors representing various cross sections.
