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.
