Claim One:
1. A system comprising: a first image generator that generates a first radar image from a first signal, the first radar image comprising a first pixel having a first energy, a second pixel having a second energy, and a third pixel having a third energy; a second image generator that generates a second radar image from a second signal, the second radar image comprising a fourth pixel having the first energy, a fifth pixel having the second energy, and a sixth pixel having a fourth energy; a pixel selector, wherein the pixel selector is configured to: receive the first image and the second image; combine the first image and the second image to form a composite image: the composite image comprising: a seventh pixel, wherein the seventh pixel is located at a position at which the first pixel and fourth pixel are co-located, whereby the seventh pixel having a fifth energy, the fifth energy is a function of the first energy of the first pixel and the first energy of the fourth pixel; an eighth pixel, wherein the eighth pixel is located at a position at which the second pixel and the sixth pixel are co-located in the composite image, wherein the eighth pixel has a sixth energy, the sixth energy is a function of the second energy of the second pixel and the fourth energy of the sixth pixel; a ninth pixel, wherein the ninth pixel is located at a position at which the third pixel and fifth pixel are co-located in the composite image, wherein the ninth pixel has a seventh energy, the seventh energy is a function of the third energy of the third pixel and the second energy of the fifth pixel, and the ninth pixel is located at a different location to the eighth pixel in the composite image; and compare a first minimum energy of the eighth pixel and a second minimum energy of the ninth pixel in the composite image with a threshold energy, wherein the first minimum energy of the eighth pixel is a minimum energy of the second energy of the second pixel and the fourth energy of the sixth pixel, and the second minimum energy of the ninth pixel is a minimum energy of the third energy of the third pixel and the second energy of the fifth pixel; determine at least one of the first minimum energy or the second minimum energy is less than the threshold energy; and based upon the comparison, identify the second pixel and the fifth pixel as being spurious energy pixels.
