This indicates that the stressing single pulse peak power requirement (i.e., mis-
sile detection) exceeds . This value for the single pulse peak power is
high for a mobile ground based air defense radar and practical constraints
would require using less peak power.

In order to bring the single pulse peak power requirement down, one can use
non-coherent integration of a few pulses per frame prior to calculating the
frame probability of detection. For this purpose, the program
Ð myradar_visit2_2.mÑ can be used again. However, in this case

n P > 1 . This is

analyzed in the next section.

2.10.2.2. Non-Coherent Integration Design Option

The single frame probability of detection can be improved significantly
when pulse integration is utilized. One may use coherent or non-coherent inte-
gration to improve the frame cumulative probability of detection. In this case,
caution should be exercised since coherent integration would not be practical
