By using metric wave Doppler fuzes technique, this paper designs a signal pro-cess ing circuit for multiple USES HEAT.

The wave function of free electron in a strong laser plasma is obtained by solving exactly the Dirac equation in a curved space-time with optical metric for the laser plasma.

A new method for height finding using monopulse measurement based on stepped-frequency system is discussed in this paper for enhancing low-altitude detection of metric-wave radar.
