A method of determining an aim point of a firearm or simulated firearm at a time of firing by continuously pulsing a laser coaxially aligned with a barrel of the firearm or simulated firearm. The aim point is then continuously detected by a camera system observing the target. A shot firing event is detected and the last detected laser pulse location on the target prior to the shot firing event is determined. The aim point of the firearm or simulated firearm at the time of firing is extrapolated from the last detected laser pulse location and at least one laser pulse location prior to the last laser pulse location.

An improved projectile trap assembly includes a frame that supports a channel and a containment chamber. The containment chamber has an ingress point receiving a fired bullet and an egress point for distributing the bullet. The containment chamber is supported by a pair of bulkhead plates that are connected to the frame. Each bulkhead plate defines an aperture, with a scroll assembly being mounted between bulkhead plates proximate the aperture. The scroll assembly includes a front scroll affixed and a rear scroll detachably connected to the bulkhead plates. A side plate is detachably connected to the bulkhead plate opposite said front and rear scrolls to seal the scroll assembly to receive bullets. The containment chamber additionally includes upper and lower trap plates that are positioned proximate upper and lower channel plates at the ingress point. Finally, a plurality of collection buckets positioned below said front scroll in an adjustable position.

The antenna includes an antenna body, comprising a conductive material, having a cavity surrounded by intersecting wall segments. The wall segments include a rear plate and a face plate having a planar array of longitudinal slots, and both plates are positioned in spaced-apart parallel planes. The antenna further includes a center wall, centrally placed between the face plate and the rear plate, to form within the cavity a parallel pair of waveguide channels. The center bar has a center bar opening extending longitudinally along a portion of the center bar, thereby separating the center bar portion into first and second center bar segments. A guidance hole is aligned with an edge of the center bar and extends through the first center bar segment and at least a portion of the second center bar segment. A probe distributes radio frequency (RF) energy in substantially equal phase and amplitude to the waveguide channels via the center bar opening. The probe includes a probe pin, which is inserted within the guidance hole and passes through both the first center bar segment and the center bar opening and into the portion of the second center bar segment. The geometry of the probe design supports the coupling of the RF energy to the center bar opening and into each of the quadrants represented by the pair of waveguide channels.
