Abstract: Disclosed is an example for determining a projectile trajectory with at least two sensors. In one example, the projectile trajectory is estimated using a first sensor having a first angular range. Further, the projectile trajector is estimated using a second sensor having a second angular range. The first sensor and the second sensor are disposed on a platform at different spatial locations. Furthermore, a discrepancy in the projectile trajectory is determined when the projectile moves from the first angular range to the second angular range. The discrepancy is created due to the different spatial locations of the first sensor and the second sensor. An actual projectile trajectory is determined by compensating for the discrepancy in the projectile trajectory using the estimated discrepancy.
