MOVING TARGETS

The object of any radar system is to track approaching targets.

These targets may be enemy aircraft, ships or vehicles, targets to be identified and disposed of. They may also be friendlies to be protected.

Radars are also used to track approaching storms to protect the citizens of a community from the vagaries of inclement weather. They are used at airports to organize and track incoming and outgoing flights. They are essential in collision avoidance on sea and in the air. Ships use them to manage intricate channels.

An ordinary pulse radar tracks a target by measuring the change in range as the target approaches or recedes.

The Fredwal Moving Target system incrementally delays the return along the radar axis to simulate either an advancing or receding target. The host radar can lock on to this target and verify its ability to track it over a specified range at the selected velocities.

Fredwal can assemble targets using an incrementing /decrementing orbital delay that reproduces the change in range generated by these moving echoes.

Fredwal targets can be used to test, verify and calibrate the circuitry that the radar system uses to track these many types of signals.
For example, range resolution is a measure of the ability of a radar to maintain lock on a selected target as a competing target approaches. This measurement can be made by combining the moving delay with a reference delay, thus generating two simultaneous returns from the same transmitted signal differing only in range.

No other target system is as effective in simulating the actual moving target!
