AUTOMATIC DETECTION AND DISPLAY EQUIPMENT FOR MOVING TARGET INDICATION (ADDEM)
L. L. Schoenfeld · 1966
Abstract : This is the first quarterly report documenting the development of an Automatic Detection and Display Equipment for Moving Target Indicator (MTI). The equipment will contain 10 range gated channels; each channel containing 10 bandpass filters to cover the audiospectrum. Moving target information will be displayed on 'B' type and doppler displays. An investigation of active filters was undertaken and a preliminary configuration selected for test. This circuit makes use of integrated operational amplifiers. In addition, the S-plane pole position for all 10 bandpass filters was calculated. Effort was also expended on development of a +10,000-VDC power supply for the storage-display tube. A 10-kz, solid-state inverter driving voltage multipliers and rectifiers was selected for test. A small variable transformer was also developed to provide highly efficient adjustment of voltages. An input voltage regulator was developed and, through use of a special configuration, a regulating efficiency of 95% was achieved. Other development work consisted of preliminary test of an integrator- threshold circuit and the target generator and doppler modulator portion of a radar simulator.
