A toy fire control radar which could track an object automatically, made with Raspberry Pi's RP2040. Please check the detailed documentation and code at: https://github.com/megatops/arduino_toys/tree/main/radar

EXPANDED TECHNICAL DETAILS

Automated Defensive Target Acquisition

This project replicates the logic of naval "Fire Control" systems by using ultrasonic sensors to track and "Lock-on" to moving targets.

  • Continuous Tracking Logic: The Arduino rotates a high-torque servo to keep an ultrasonic sensor pointed directly at the closest moving object. The firmware uses a "Predictive Tracking" algorithm to stay ahead of the target's movement.
  • Firing Sequence Trigger: (Simulated) Once a "Lock" is achieved for more than 2 seconds, the Arduino triggers a separate output (like a Laser or LED), signifying a successful target acquisition.

Field Calibration

  • Sensitivity Thresholding: Includes a software filter to ignore stationary objects (like walls), ensuring the radar only reacts to mobile "Intruders" within its 4-meter range.
