    • PURPOSE: To obtain a small angle detector mountable to a vehicle or the like, by providing a transmitting means for transmitting a specified wave to a plane to be detected and two receiving means to calculate the angle checking the phase difference between received signals.
      CONSTITUTION: A transmitter 40 which transmits a specified wave to a plane 300 to be detected and two receivers 40 and 50 which receive specified waves reflected from the plane 30 being detected after transmitted from the transmitter 40 are set in proximity to one another apart by a specified interval (a). Out of the receivers, one 40 may be a transmitter/receiver built to serve concurrently as transmitter. In operation, specified wave received by the two receivers 40 and 50 are inputted into a detection circuit section 400 to detect the phase difference between both the received waves. The phase difference is converted into an angle pulse to be outputted as it is proportional to the angle θ between the surface where the receivers 40 and 50 are set and the plane 300 being detected.

    • PURPOSE:To suppress the influence due to multipulse and to improve height measurement precision by finding the mean value of received signals against transmitting pulse signals with specific different frequencies, estimating direct waves, and making a measurement of height. CONSTITUTION:Route length difference DELTAR between indirect and direct waves are found from the range between a target and a radar obtained from a range finder in a target tracking state, and two transmission frequencies which satisfy the frequency difference DELTAf shown by an equation are set. A transmitter outputs transmit pulse signals of those two transmitting frequencies successively. Received power signals P1 and P2 as corresponding reflected signals are composed of indirect waves fI1 and FI2, and direct waves fD1 and fD2 on vector basis, so they are averaged to estimate the power of the direct waves fD1 and fD2; and the elevation to the direct waves are found and the height is measured from the elevation and range information.

    • PURPOSE:To make the operation of a radar equipment easier and improve the plotting accuracy of the equipment, by performing the plotting operation by reading out stored information of the position and time of a target at every beam screen with a cursor fitted to the target echo displayed on a radar indicator. CONSTITUTION:The position information Rn and Az and time information (t) of a target are supplied to a control circuit 31 and stored in memories 32L, 32M, and 32U corresponding to each beam screen. The information is updated at every prescribed time. When an operator operates a beam screen designating switch 15 while putting cursors 13 and 14 to target echoes EL, EM, and EU displayed on a radar indicator 11, position signals RC and AC and a beam screen designate signal SIV are supplied to a separating section 33 through the control circuit 31 and a memory corresponding to the designated beam screen, for example, 32L is accessed and information in a prescribed range is read laying stress on the signals RC and AC. Then from plural information, whose time information (t) coincides with each other, a mean value is found at a central value operating section 34 and the plotting operation is performed at a plotting operating section 35 based on the mean value.

    • PURPOSE:To expand elevation coverage and to improve the performance in suppressing clutter in the high elevation coverage by combining a main electronic scanning array and an auxiliary electronic scanning array which takes charge of the high elevation coverage. CONSTITUTION:The respective phase shifters 2A, 2B of a main electronic scanning array 1A which is swiveled integrally by a reference signal generator 7 and a beam control circuit 5 and an auxiliary electronic scanning array 1B which takes charge of high elevation coverage are controlled synchronously. The vertical coverage is combined with the elevation coverage, whereby said coverage is expanded without increasing the scanning speed. A moving target which radiates two sets of transmission outputs differing in frequency is detected with the auxiliary electronic scanning array of a relatively short range, whereby the performance in suppressing clutter is improved.
