Given a sensor network's capability to closely track a ship's emitters, how would an operator use this information to best avoid being tracked, while keeping an emitter on as long as possible...

In an earlier blog we demonstrated a Maximum Likelihood (MLE) method to model the accuracy of an electromagnetic sensor network against a non-maneuvering mobile emitter. In this model, we apply a Kalman filter...

In previous blogs we described an approach to find a path that minimizes detection of its emitters using Fuzzy Logic. In this entry we describe an algorithm that uses a platform's radar cross section (RCS)...

Last month's blog demonstrated an algorithm that produced a "Fuzzy Path" that reduced detection without unnecessarily extending the distance to reach a destination. The user requirements...

If an operator has a reasonable estimate of an adversary sensor system's capability as shown in LOB Error Method and TDOA vs AOA Error Comparison how can he/she use this information to avoid detection...

Using our models to assess the errors for an angle-of-arrival (AOA) system and a time-difference of arrival (TDOA) system we created this view to dynamically display the two systems against a mobile emitter...

We compare our implementation of the Discrete Probability Density (DPD) method [Poisel] with two maximum likelihood estimation (MLE) methods. The DPD uses a von Mises probability density function (PDF)...

We have used the IDEF0 diagram for a variety of different products over the course of many development efforts. These efforts include development of the first operational architecture for....

With our partner, Princeton Satellite Systems, we developed ControlPlan under an SBIR for Navy PEO Space. The software was developed to demonstrate the ability to use mathematical optimization methods to support operational planners....

Although ControlPlan was developed as a demonstration of an innovative planning technique within an SBIR under Navy PEO Space, our development team worked to include....

We established several objectives within our SBIR with Princeton Satellite Systems to develop a “Reconfigurable Satellite Planning Tool” for Navy PEO Space. We had to....
