Abstract

PURPOSE:To remove multipulse effect for low-altitude targets by using one of the receiving antenna elements disposed in a vertical direction for transmission, too, and subjecting the respective received signals to prescribed phase correction then complex-adding these. CONSTITUTION:The signals received by N-1 pieces of receiving antenna elements 19... disposed at prescribed intervals in the position of a height hi in one row in a vertical direction and the transmission-reception antenna 18 of the lowermost position etc. as well as the distance measurement information R0 etc. by a transmission- reception switching machine 22, a transmitter 21, a distance measuring device 23 and a receiver 23 are applied to a signal processing device 24. These received signals are phase-corrected by the coefft. ti based on the equation I and are subjected to complex-addition processing. Thereby, the multipulse effect by the indirectly reflected waves 10... from a low-altitude target 7 reflected from the sea surface etc. 11 is removed. Hence, the highly accurate detection and tracking are accomplished for low-altitude objects as well. In the equation, theta0 is the variable in signal processing, K is a constant and lambda is transmission wavelength.
