A register stores a return time that indicates a time the CPU is to be switched from one of the power-saving mode and the sleep mode to the normal mode. A comparator compares the current time of the clock with the return time of the register, and outputs, when a match occurs, a control signal to the CPU so that the CPU is switched to the normal mode.

It has been found that target optics produce non-specular, augmented optical returns when interrogated by a laser pulse. This non-specular radiation is detected by an active laser search system employing a direct-reading, thresholded focal plane detector that is able to detect non-cooperating targets with optics that employ a detector or optical element at the focal plane of their receiving optics. The pulses returned from such target optics have a width commensurate with the original transmitted pulse width, whereas passive background noise and the spread out active returns from the ground exhibit temporally long returns. By setting the sensor threshold sufficiently high, the system discriminates against noise and clutter while at the same time reducing the number of sweeps required to detect a target within the search area.
