A C-182 pilot flew an ILS chasing the localizer and glideslope as ATC issued course and altitude alerts. He continued to landing because he had intermittent ground contact but later realized he should have executed a missed approach when he found his ILS was faulty.

Narrative:
I was on the ILS and was chasing the localizer trying to keep it centered. I had no problems following the VOR enroute to the field. Tower gave me numerous corrections and even an altitude alert at one point; but because I could see the water below me and land ahead of me I continued the approach to a landing. Quite honestly I should have missed the approach. My next destination was VFR and I requested vectors for the ILS. I tuned the number one and number two ilss to the same frequency and discovered that the number one ILS receiver was all over the place while the number two receiver operated normally. On the approach to my destination I had set the number two receiver to what I thought would help me the most on the approach. What I should have done was backed up the number one receiver with the number two receiver. Barring that; I should have missed the approach. I will learn from this mistake. Use all available resources to safely fly the approach. The number one ILS receiver is being repaired. Since submitting the above report; I have been 'chair flying' this approach in an effort to learn from and never again repeat my mistake. I would like to add the following:I chased the needles as stated above; but failed to realize that the receiver was bad. Because I never pegged the needles; I assumed I was flying through the localizer and glideslope and kept trying to correct my flight path. After the first couple of tries at correcting my flight path I should have realized that something was drastically wrong and missed the approach. As far as backing up my approach with the number two receiver; that is absolutely correct; but I had more tools available. I could have programed the GPS to the GPS approach to 16R and when I realized that things weren't right I could have asked for the GPS approach and flown that with the number two ILS as backup. Also I had my ipad with foreflight and the moving map display up and could have monitored my progress on the approach plate and realized my situation much sooner.as I noted before. I have learned much from this mistake and will never repeat these errors again. Always use all available resources. And miss the approach if the flight becomes unstable thank you

Quite honestly I should have missed the approach. My next destination was VFR and I requested vectors for the ILS. I tuned the number one and number two ILSs to the same frequency and discovered that the number one ILS receiver was all over the place while the number two receiver operated normally. On the approach to my destination I had set the number two receiver to what I thought would help me the most on the approach. What I should have done was backed up the number one receiver with the number two receiver. Barring that; I should have missed the approach. I will learn from this mistake.
