Abstract

PURPOSE:To improve the accuracy of searching and tracking a low-altitude target by processing the signals received independently by plural pieces of antennas disposed in a vertical direction by a prescribed system thereby removing multipulse effect. CONSTITUTION:N pieces of antennas 18... disposed at a height hi on a straight line in a vertical direction are corresponded to the transmitter-receivers 19... which are synchronously driven by a synchronous generator 23 respectively at a transmission frequency ti. The detection outputs of the angularly radiated pulses received independently by these transmitter-receivers 19... and the distance measurement information R0 etc. by the lowermost antenna 18, the transmitter-receiver 19, a distance measuring device 20 etc. are added to a signal processing unit 21, and the respective detected outputs are corrected by the correction coefft. ti based on the equation I and are complex-added. Thereby, the multipulse effect occuring in the image target 8 based on the indirectly reflected wave pulses by the reflection of a low- altitude target 7 from the sea surface 11 etc. is eliminated, the accuracy for low- altitude targets is also improved, and the searching and tracking by monopulses are accomplished. In the equation, K is a constant and C is the velocity of light.
