A digital SAL receiver implements a multiobject tracking method to detect EM pulses transmitted by a known source at a pulse repetition interval (PRI) and returned off of a target object to acquire multiple tracks. Intra and inter track temporal information is used to associate pulses with different tracks and to rank the tracks in order to designate a primary track for the target object.

An all-digital line-of-sight (LOS) process architecture addresses the size, weight, power and performance constraints of a receiver for use in semi-active or active pulsed electromagnetic (EM) targeting systems. The all-digital architecture provides a platform for enhanced techniques for sensitive pulse detection over a wide field-of-view, adaptive pulse detection, LOS processing and counter measures.

Methods and apparatus for processing data from multiple sources according to various aspects of the present invention include a sensing system for determining target information. The sensing system includes sensors to generate target information and local trackers to receive the target information from the sensors. The local trackers may generate local target data for the target, and a combiner connected to the local trackers may use the local target data to generate global data for the target.

Methods and apparatus for processing data from multiple sources

A vehicle security monitoring device monitors sound or movement within a vehicle to determine an abnormal condition such as intrusion of a thief. Upon determination, the device transmits sound picked up within the vehicle to a portable monitor unit carried by the owner of the vehicle using a dedicated link without using any communications network. The transmitted sound allows the owner to distinguish between an actual intrusion and false alarm. Upon verification of an actual intrusion, the portable monitor unit allows the owner to send various instructions to prevent theft of any valuables in the vehicle or theft of the vehicle itself. The instructions may include playing of warning messages, activation of a siren and disabling of the vehicle.
