Latest Patents

Suhler's latest patents include the "Acoustic Amplitude-Doppler Target Ranging System" and the "Acoustic Amplitude-Threshold Target Ranging System." The Acoustic Amplitude-Doppler Target Ranging System is designed to automatically detect military targets and provide a munition firing signal at the appropriate target position and time. This system utilizes an amplitude-doppler circuit to predict the time of closest approach of a target to a munition by measuring the time interval between zero crossings of the second and third derivatives of the received acoustic wave amplitude function. The circuit produces a firing signal by logically ANDing the closest point of approach signal with a signal indicating when the target range is within specified limits. The system is realized using conventional electronic zero crossing detectors, an up-down counter, dividers, sample and hold devices, and voltage comparators. The acoustic target signal is obtained from an omni-directional microphone, the output of which is amplified and rectified.

The Acoustic Amplitude-Threshold Target Ranging System generates munition actuation signals by predicting the time and distance of closest approach of a moving target to a munition. This predictive capability is based on the rate of change of the sound level emanating from the target compared to its absolute magnitude. The system generates standby, arm, and fire signals by differencing the received acoustic amplitude function signal and its first derivative, subsequently comparing the difference signal with various reference level signals. These reference level signals are a function of munition effective range and target conditions. The mechanization of the system is achieved through simple circuitry, which includes an acoustic signal detector and processor, a differentiating operational amplifier, a programmable gain amplifier, a reference level signal source, an adder, and a comparator circuit.
