Abstract:
A system, having at least one external interface and at least one output interface, for dynamically simulating a real-time response signal of a detector viewing a scene that may be captured as at least one image composed of a first configuration of pixels, each said pixel having an intensity to which an intensity value may be assigned and a base address value that may be assigned, comprising:a first memory in operable communication with said external interface,wherein said first memory may store said first configuration of pixels;a map generator, having an input and an output, for producing at least one map representing as a second configuration of pixels said simulation of a real-time response signal, each said pixel of said second configuration of pixels having an intensity for which a intensity value may be assigned and a base address value that may be assigned, said base address values having both an integer part and a fractional part, in which either said integer and fractional part may include zero,wherein said map generator may operate off line,at least one second memory in operable communication with said map generator and said address generator and external to each,wherein said at least one second memory stores at least part of said second configuration of pixels as at least one detector response map value;a gyro model at least in operable communication with said at least one external and said at least one output interfaces,wherein said gyro model establishes an error correction from which an address offset may be calculated and provides gyro position information;an address generator that incorporates at least one first processor and at least one addressable memory for storing said base address values of said second configuration of pixels, said address generator in operable communication with said gyro model and said map generator,wherein at least one pixel selected from said second configuration of pixels is selected for modification of said selected pixels' said base address value, wherein said address generator receives said address offset from said gyro model, wherein said at least one first processor provides said integer part of said modified base address value of said selected pixel of said second configuration of pixels to select at least one pixel of said first configuration of pixels, andwherein said at least one first processor provides said fractional part of said modified base address value of said selected pixel of said second configuration of pixels to select at least one said detector response map value from said second memory;at least one second processor in operable communication with said at least one first memory and said at least one second memory,wherein said second processor multiplies said intensity values for each said selected pixel from said first configuration of pixels by corresponding said intensity values for each said selected detector response value to generate at least one resultant value of pixel intensity,wherein said second processor sums said at least one resultant values to generate at least one convolved image, andwherein said at least one convolved image may be generated as a series of convolved images that move in synchronous relation to said at least one imaged scenes provided in real time to dynamically simulate said detector's response to viewing said at least one imaged scenes as they are presented; andat least one reference in operable communication with said at least one first memory, said at least one second memory, said address generator, said gyro model, said at least one second processor, and said map generator.
