Theory of conicalscan radars for lowangle tracking dtic. Conical scanning, radar tracking in microwave and radar. In, it is explained that in terms of angle error, two techniques of sequential lobing and conical scan are similar to each other. Sequential lobing, radar tracking in microwave and radar. The range and doppler frequency shift can also be continuously tracked, if desired. Angle tracking conical scan, sequential lobing, low. You can generate a conical scan pattern, as shown in figure 1, by using a rotating feed driven by a motor in the housing at the rear of the dish. Some older target tracking radars use the conical scan to determine the exact target direction. If the antenna beam continuously rotates for tracking a target, then it is called conical scanning. In this video, i have explained conical scanning in radar tracking with following aspects.
Draw the block diagram of a pulsed radar and explain its operation 2. Following figure shows an example of conical scanning. Conical scan modulation is used to find the position of the target. This chapter describes the conicalscan, sequentiallobing, and monopulse. Conical scanning conical scanning 1 an alternative to sequential lobing is to rotate the antenna beam around the direction of the target on a continuous basis. Compare and contrast conical scan and sequential lobing type tracking techniques. A tracking radar n t e n a t i h i e s o t r y d e s i g n. To track a target in one axis, two lobes are required. Error signal produced when the target is on the tracking axis for conical scan. Distinguish between sequential lobing and conical scan.
