BioSAR30
ZAI's patented and trademarked BioSAR30 is a low frequency airborne synthetic aperture radar system that rapidly and accurately measures terrestrial biomass in heavily wooded areas. The system operates in the VHF spectrum and senses only the trunks of large trees since the limbs and leaves are transparent at the VHF frequencies used.

Robotic Vision System
ZAI designed, developed, and patented an automated robotic vision system that uses two light sources and a digital camera mounted co-linearly on a platform. It is very simple and inexpensive to operate. Capturing 30 frames per second, the system forms two images for each frame. One image is a standard TV image in a raster format. The second, simultaneous image has exactly the same image data; however, the data is encoded differently. The ranges to the objects at each pixel within the frame are encoded in the intensity of the image on a pixel-by-pixel basis forming a three-dimensional map.

SmallSAR
ZAI's SmallSAR (Small Synthetic Aperture Radar) is a vehicle-mounted short range radar for the detection of buried and non buried improvised explosives devices and explosively formed projectiles by the roadsides. The radar system is specifically designed for standoff, real-time detection and imaging of roadside threats and low and medium speed (0 – 20 KPH) to assist in road clearance missions. SmallSAR uses Ultra Wide Band (UWB) technology to provide unprecedented range resolution across the area in front and to the side of the host vehicle.

Soldier Identification System
ZAI's patented Soldier ID system is used to identify friendly forces. It consists of two parts. The first part is a beacon worn by the troops; the second part is the interrogator - a receiver/detector that is used to observe the unique beacon signature. The beacon is clipped onto the soldier's lapel. It emits a coded and encrypted spread spectrum signal. On the other end, the receiver/detector can be hand-held or mounted on a rifle barrel similar to a scope.

Target Recognition System
ZAI designed and developed an airborne target recognition system that uses the nose-mounted Vidicon camera installed in an aircraft to capture images of unknown target aircraft. Images of unknown aircraft from the camera are processed and compared against a parallel CAD/CAM look-up library using a high-speed linear array processor to make the identification. Its high level of accuracy and quick performance make it a valuable addition to fighter aircraft detection systems.
