The invention discloses a collaborative ranging prototype design method, and relates to the technical field of high-precision time synchronization. The method comprises the following steps that a computer controls a master node to transmit signals according to designed time slots, and slave nodes enter a network access mode until master node signals are captured and locked, and initial time synchronization information is obtained; the computer controls the synchronized slave nodes to enter a networking working mode; and the computer controls each node to carry out data transmission and measurement signal transmission in the own time slot. According to the invention, a broadband spread spectrum system is adopted, a wireless time transfer link with high anti-interference and covert communication is established, the anti-interference capability of the system is improved in combination with an anti-interference data processing algorithm, safe and reliable communication service is provided through the broadband sp
