Techniques and apparatuses are described that implement a multi-radar system within a device and optimize operation of the multi-radar system. The multi-radar system includes two or more radar circuits located at different positions on the device. The multi-radar system also includes an optimization controller, which controls operational states of the radar circuits. In particular, the optimization controller determines respective operational states of the radar circuits to optimize performance of the multi-radar system under certain constraints. For example, the optimization controller can alter the respective operational states for different radar circuits responsive to detecting various trigger events. In this way, the optimization controller can selectively alter the operational states of the radar circuits for various situations.

Modern high velocities and altitudes of long-range projectile launch require a new device capable of predicting the exact geographic location and speed on impact instead of tracking object (or debris) by a radar all the way to the impact.

The principle of design for such device was achieved through rigorous application of the classical dynamics for non-inertial reference frame rotating with constant angular velocity.

It allowed, based on planet mass and rotational speed together with geographic coordinates and conditions of launch, to significantly improve ballistics accuracy by precisely forecasting behavior of a free falling objects or unmanned capsules in vicinity of a chosen planet under different atmospheric conditions.

Providing radar or a sensor compatibility with the proposed device, their performance will be enormously improved by enabling them to point at exact search, rescue, or evacuation area ahead of time.
