Overview of Radar Tracking & Techniques 22011A0436 Yashwanth Rao Ramavarapu
Introduction to Radar Tracking Radar tracking involves detecting and following objects using radar signals. It utilizes reflected signals (echoes) to determine an object's position, distance, and movement, making it essential for accurate monitoring and navigation.
Types of Tracking Radars Radar tracking is achieved through various methods. The five main types are: 1 Sequential Lobing 2 Conical Scan 3 Monopulse Tracking (Amplitude Comparison) 4 Monopulse Tracking (Phase Comparison) 5 Range Tracking
Sequential Lobing Radar The antenna beam alternates between two positions ('lobes'). The target's position is found by comparing the signal strengths from these lobes. Advantage: Simple design Limitation: Slower updates
Conical Scan Radar The antenna beam rotates in a small cone pattern around the target, continuously adjusting to keep the target centered. Advantage: Smoother tracking Limitation: Errors if signal fluctuates
Monopulse Tracking Radar (Amplitude Comparison) This method uses multiple beams simultaneously, comparing their signal amplitudes to precisely locate the target. High accuracy in one or two coordinates Advantage: Resistant to signal fluctuations
Monopulse Tracking Radar (Phase Comparison) This advanced technique utilizes the phase difference of received signals to provide highly precise angular measurements. Very accurate and fast Advantage: Excellent for defense & aerospace systems
Range Tracking Radar Range tracking radar continuously measures the distance to the target, using echo return timing to update the range. Advantage: Accurate distance tracking Used in missile guidance and target ranging
Summary Sequential Lobing Simple, but slower updates. Conical Scan Smooth tracking, but less robust to signal fluctuations. Monopulse (Amplitude/Phase) Most accurate, but more complex. Range Tracking Specialized for precise distance measurements.
