Abstract: A generic interface test adapter for connecting between a test station and a unit under test. The generic interface test adapter includes an interface frame and an interchangeable circuit card assembly that are configured to route the signals between test station and the unit under test. The interface frame includes an interface plane having a plurality of contact pins or spring-loaded probes, and the circuit card assembly has a plurality of contact pads, aligned to mated with the contact pins. The electrical connections between the test station and the unit under test can be reconfigured merely by changing the interchangeable circuit card assembly. A pressure frame is provided to securely hold the circuit card assembly against the interface plane to provide electrical connection. The pressure frame is pulled toward the interface frame by a cam and angled cam slot mechanism operated by a lever arm.

Abstract: A low cost easily deployed, yet highly accurate weapon mounted trajectory analysis radar system uses optimized Doppler radar signals to detect the actual trajectory of a projectile fired from an artillery piece such as a 155 mm Howitzer. The actual trajectory data is used to determine an atmospheric model that may be used to aim the weapon for future firings. The system includes a Doppler radar system having a turret mounted antenna that tracks the projectile, a digital signal processor using a FFT to convert radar pulses to trajectory data and a data processing system that analyzes the trajectory data to develop a true atmospheric model.
