The Army wants to give its Apache attack helicopters a better ability to spot non-moving ground targets with its fire control radar.

When it comes to detecting stationary targets while the Apache is moving or hovering, the helicopter has a problem.

"While this capability currently exists, it is limited due to inherently large clutter backgrounds, low probability of intercept (LPI) requirements, operating frequencies, and limitations to aperture size," according to the Army research solicitation.

So the Army wants to develop better algorithms for the Apache's radar. The Army is particularly interested in "a novel algorithm approach rather than data collection concepts to improve detection (such as Doppler beam sharpening or synthetic aperture radar) using current or similar algorithms."
