The real-time test system of the radio fuze

The radio fuze used in a strategic missile weapon system is a pulse radar altitude-meter. To avoid the difficulty in testing the radio fuze of a missile warhead, the paper introduces a new real-time test method. It uses a PC to simulate the echo data of target. Under the control of the PCI bus, the simulated echo data is passed to a high-speed DAC which can generate a video signal. The video signal is used to modulate the RF oscillator to generate an RF signal. With this technique, we can greatly simplify the testing procedure and shorten the testing time, compared with conventional techniques.
