" ABSTRACT
This report contains user instructions and program listings for multiple leg Kalman Filter target motion analysis (TMA) procedure for use on the … Sharp PC-1500 (Radio Shack TRS-80 PC-2) …

I. INTRODUCTION
     This report contains a multiple leg target motion analysis (TMA) program for each of the following portable computers: … the Sharp PC-1500 (Radio Shack TRS-80 PC-2 …
     These programs provide a means of implementing a TMA procedure that is described in Appendix I. The procedure requires at least four bearing observations. It is assumed that during an encounter, the target course and speed remain constant, and that signal transit times are zero.
     This algorithm is a Kalman Filter adaption of the least squares TMA algorithm given …

IV. THE SHARP PC-1500 (RADIO SHACK TRS-80 PC-2).

                         [SHARP PC-1500 (TRS-80 PC-2) USER INSTRUCTIONS
     There are three main user options. These options - labeled 1 2, and 3 - are used to continue input, input a new leg, and to compute a fix, respectively. Other options include unit selection (n. mi., yds. or meters) and AOP selection. Their use is shown
below. (Memory: 2050 bytes for program; number of bytes for variables is not available.)
