AI Technical Summary
Conventional radar target tracking algorithms cannot predict the position of high-speed targets, making it easy to lose targets. Furthermore, expanding the radar's sensing field can lead to energy dispersion and reduced detection range.
By acquiring radar echo signals from each radio frequency channel, packaging and FFT processing are performed to calculate the velocity spectrum. The target position is determined using a preset velocity window and servo turntable angle. A tracking prediction function is then constructed to predict the servo turntable angle to achieve stable target tracking.
It enables the measurement of velocity, angle and position of high-speed targets, avoids target loss, is applicable to traditional mechanical radar and phased array radar, has the ability to distinguish non-targets of interest, and is not prone to false alarms.
