Abstract: An actively powered wearable weather radar detection device may include a battery, at least one microstrip antenna, and a microcontroller electrically coupled to the battery and the at least one microstrip antenna. The microstrip antenna may be configured to receive a weather radar signal from an airplane, convert the weather radar signal into an electrical signal, and output the electrical signal. The microcontroller may be configured to determine, based on the electrical signal, whether to output an alert signal, and responsive to determining to output an alert signal, send a command signal to an alert device causing the alert device to output the alert signal.
